The '60/70's =
1963
- The
eclipse that started it all -- my first totality, from
Dexter,
Maine. From reading
the small but charming "Stars"
Golden Guide when I was growing up, and a few other
astronomy books in the Deborah Cook Sayles Library in
Pawtucket, I'd learned that every now and then something
really astonishing occurs in nature. But you must prepare in
advance, be willing to travel to a particular place, and on
the day it happens find a clear spot of sky. Not so easy.
Merely spectacular. I had to see one of these for myself!
The book listed the next decade's solar eclipses. Nuts, not
many. To a teenaged student in the smallest state, with
little money, the options were few.
As it happened, a path
crossed Maine in July of 1963. During the summer, my parents
often suggested we pile into the car for day trips when we
could, and this astro-event was too tempting not to suggest,
and then head off north. We all wanted to see one, including
a good friend, Bob Jepson. The four of us drove up to the
Bangor area, and learned the frustrating turn of events:
rain was now predicted -- ick! Very few saw anything much in
Maine that totality, except over on Bar Harbor, where the
cooler ocean air kept clouds at bay for most of the island.
Some few observers lucked into being under a hole in the
clouds, however, and we were among them. But it was not so
obvious that afternoon -- the clouds grew worse and worse as
2nd contact approached, until by 15 minutes to go we were
"totally" socked in.
We'd setup on a
lakeside hill, now cloudy, but unstable conditions and the
cooling of the moon's shadow conspired to poke a small hole
in the cloud deck, just as darkness began.
Wow!
(The fairly wide view above shows how close we came --
BTW, that's Venus shining over nearer the right edge,
peeking through a cloud wisp.) Like the big Radio City Music
Hall curtains, the clouds parted, we unforgettably witnessed
our first totality (and caught several pix) for 62 memorable
seconds. Too soon 3rd contact's diamond ring dazzled us, and
moments later, neat as you please, the clouds gently came
together again, and the sun was not seen any more that
afternoon. Show was over!
Going,
Going, GONE! (Click
any for a large view)
Five minutes later it began
to rain, and we grabbed the cameras and tripods and ran for
shelter. I was hooked: wotta
experience! (Can
you have any doubt of this when you look at the recently
found dramatic image sequence above?!) But it was not until
after college, living and working in NYC that I began to
listen to the call of the wild corona. I just missed getting
to see the 1970 totality, due to a airport screw-up with a
sick friend. Damn. "Never again!" became my battle-cry, a
shove at witnessing ALL the consecutive totalities from the
next dozen years, until the 1985 one in deep Antarctica
halted my insane "100% viewing streak," at least for few
years...
1972
- My
second totality (1963 above was the first time I'd seen the
corona), this one was observed and photographed through
clear skies in July 1972 by Rachel
Elkind and me from
the deck of the SS Olympia, in the North Atlantic Ocean, a
few hundred miles SE of Nova Scotia. The in-between corona
you see here is typical of years when the solar activity is
neither at minimum nor maximum. Often you'll find angular
"arrowhead" shapes at such times, and this in-between corona
had a dandy. It's not an uncommon shape for the corona, as
you can seen from other photos here and elsewhere taken over
the years.
There were only a few
small prominences visible this time, those pink-red flames
on the solar cusp that often peek over the moon's limb
during totality. The exposures I could use on a moving ship
were unfortunately pretty short, so, as I explain further
below and on the 1977 image, there is not a perfect
transition from coronal wisps into deep sky on this
composite. (For this computerized version I added some outer
details gleaned from several other images by friends who had
short, fast lenses -- greater reach, but low on detail. It's
still the poorest coronal imagery I've gotten.)
But
back in 1972 the only images we knew how to make were taken
with single exposures. Since writing the brief report above
I've found a few snapshots that were our "permanent" views
of this corona (actually, color images fade, so these here
had to be corrected). This is the best one can hope for
using a good camera with telescope, no fancy filters or
compositing. We had just gotten a then-new
Celestron
C-5, which is what
we used for the c.u. image at the left, and the diamond just
below. It was pretty high-powered (1250mm f.l.) for the 35mm
Topcon, especially when you consider the foolhardiness of
trying to keep it centered on the sun's disk from a moving,
pitching ship out the the North Atlantic! Being new to this,
we believed the nonsense we had been told, that kind of gear
had already been tested on board the Olympia, and it was a
VERY stable ship. Right, sure -- nothing like dissembling to
"the rubes" (that was us), to get them to support your
venture. We were at our wit's end to try to get what you see
here. Most of our shots have the image half cutoff (these
both were slightly chopped -- but I repaired the damage
after scanning the photos -- so you won't see the problem on
the site).
Also,
with that much motion you are forced to use a pretty fast
shutter speed on your camera. Everything we took of 1/8th
second or longer was blurred, some quite horribly so! And
that was while attempting the trick of waiting for the
highest moment of each sea swell, when the ship moves the
least rapidly. Oh, well, solid ground is still the best way
to do serious eclipse reconnaissance. Faster films are a
help nowadays, but a ship is still better suited for naked
eye and binocular observation. They can make it easier to
get to a good location. This eclipse was hard to see, as
most of the path experienced cloudiness. But our ship,
guided by savvy meteorologist and eclipse expert, Ed Brooks,
just managed to find us a clear spot. The good sky
conditions (thanx, Ed!) also allowed us to grab this
beautiful diamond ring as totality began. I'm glad to find
yet another diamond to put here for you to enjoy. They don't
vary quite as much as the coronae, yet each has its own
"flavor" and "personality". (I'll save the reasons for
another time.)
1973
- The
"Big One!" At the
end of June 1973 a total eclipse occurred with an unusually
long duration of 7m
04s. In the past
several hundred years there had only been one eclipse longer
than this one, the prior eclipse of the same Saros, in June
of 1955. It will take almost 500 more years for another as
long. But the totality in 1955 was longer only over water,
at 7m 08s. Where the shadow touched land it dropped to about
7 minutes exactly. By the most serendipitous of flukes, 1973
was a chance to view the longest land-based eclipse of my
life, certainly, and for many others as well. I really
wanted to do it right!
There was the small
matter of WHERE this eclipse would be visible: Africa,
across mostly the hot and difficult to reach span of the
Sahara Dessert, and neighboring central African mountains
and savanna. The maximum location was not large -- those
going to less difficult regions would be sacrificing
duration, particularly in the easiest places: the Atlantic
coast near Mauritania, and Kenya, where duration was not
even 5 minutes long. Rachel Elkind and I decided to try for
the optimum region, in the Air Mountains (it's pronounced:
"eye-ear") some miles north of Agades, a small town in
Niger, central Africa that resembles Timbuktu in appearance
and "convenience." There we timed our totality at
7m
02s, still one for
the Guinness Books...!
Here
you can see a view of our camp, near a location locals call:
"Krip-Krip", right on the center line. That's the main
"road" down below, that got us from the nearest airstrip to
the camp. Rachel and I got there via a small plane that was
piloted by a friendly, bright American missionary she
managed to contact, Pastor Kepple, who was also eager to see
his first eclipse, and made his services available very
reasonably. We wanted to capture aerial motion pictures and
stills of the region. This shot is from the SL66 camera, one
of several that I snapped while hanging out of the open
doorway (Pastor Kepple had removed it for our photography)
of the Piper Cub, restrained by a small seat belt and
Rachel's firm grip and not much else. If you think taking
the stills was risky, hanging onto a heavy, clumsy old
Arriflex 35 mm motion picture camera while we cruised over
mountain peaks just North West of here was enough to make
many of my friends turn white when I got back and excitedly
told them about our "nifty adventure!"
Back
on ground here's a moody medium format shot of our camp as
the sun set into some residual haze, and the first evening
descended rapidly upon us (note:
this is a new, much sharper, wide-angle image stitched
together from two original slides, just rediscovered and
scanned, to replace the mediocre copy of a copy version we
had posted here earlier).
Temperatures regularly dropped from a daily high of 130+
deg. F, to nighttime lows of 75 deg. F or less, which really
felt C
O L D by
contrast -- ah, desert life!. I climbed the not too steep
hill you can see to the left in the prior image to get this
view. There are many neat stories which seeing these photos
brings back with alacrity. Most will have to wait for
another longer dedicated page on this site. The blue-green
American tent in the center, by the way, fell down the
second day (but NOT Mr. Kantana's bigger one!). I had slept
soundly in it the first night. We trusted some other
Americans who joined us to help set up the tent (Rachel and
I sure didn't know this kind of stuff...!) In the stiff
breezes of this location one needs lash the posts from
slipping apart (we learned this weeks after we had gotten
back home. Our friends didn't take this precaution, and so
it all blew down and bent the aluminum poles!
(The tent is
dead; long live the Tuareg huts...!)
Here's
the really practical wind shelter that wonderful,
enterprising Mr. Kantana built for us with his crew the day
before totality. Rachel had managed to meet him in Niger
somehow (he was a real desert-rat / local school supervisor)
to set up a camp on an earlier trip out there (an
adventure-trip during which she met her future husband, Yves
Tourre, in fact!) Wind and dust and sand were a constant
problem, and this native-style construction of woven mats
sewn to large sticks planted firmly into the ground, like
the "huts" worked surprisingly well. They would wet them and
the ground-mats to cope with the dust. It worked.
You can see the black,
upright Nikkor 1200 mm lens with the SL66 Rollei below, the
units nearest us in this pix I took right after the eclipse
ended (with the camera missing here from the upper orange
C5.) That's a polarizing disk with color-coded filters on
the top of the Nikkor that I cobbled together at home prior
to the trip. I also built the metal mount for the Arriflex
35C motion picture camera in the middle. As all our gear was
equatorially mounted and driven (I'd never be so
overambitious today--phew! ;-) the Arri, which we rented,
had to be modified to go on one of the Celestron tripods,
and to hold the Zoomar 500 mm lens. I made a rotating N.D.
filter you can see on top of this lens. It went from a heavy
density of 4.0 to nearly clear 0.1, depending on the angle.
I could set just enough light to reach the movie film and no
more -- a neat trick.
In the rear are two
Celestron C5 telescopes, piggyback mounted (tricky to align
such a rig!). One of two Topcon cameras had Color InfraRed
film in it, a curiosity I had also tried in '72, the other
had high res color slide film in a 250 exposure back, with
motor drive, for time lapses of the partials. The filter on
the top is a special Hydrogen-alpha filter (an early one
made by expert Del Woods) which allows you to photograph
prominences even without an eclipse, and the solar
chromosphere's details. I also assembled a second deep green
filter, with fussy alignment prisms, to add more colors to
the deep red of H-alpha, giving an orange sun with red
through green details.
This
is the lovely intermediate-type corona we witnessed there in
the desert that Summer near noon (not a cloud in the sky,
just some dust haze.) The moon and sun almost exactly
overhead (only 1991 was actually at the zenith, a few more
degrees "up") which is not too easy on the neck to view! The
SL66 had both a standard back and one I modified with a
home-built "radial-gradient neutral-density filter." I got
the concept from the same Gordon Newkirk who wrote me the
generous letter way above. It squeezes the immense
brightness range of the corona into one more manageable by
mere photographic emulsion. There are many tradeoffs, and so
after inventing several ways to get the same result with
darkroom compositing, I stopped using such awkward
filters.
This image had to be
painfully reconstructed digitally recently from the original
negatives, which were not up to my usual standards (I had
gotten quite dehydrated the day before and was not yet
recovered.) My rad-grad filter gave a green color cast near
the limb which I corrected here. Several dust specks got
onto it (static electricity?) and they show up on the negs!
Rad-grads! But one beautiful image down below from 1998
started out from two excellent negatives Jonathan Kern took
using a rad-grad filter he made himself: metal evaporated
onto glass. I may try one again the next eclipse, as he's
offered to make me one. It will be a lot better than what I
could do at home myself with film emulsions and time-exposed
rotating masks...!
The
final proof that we were right on the centerline is easily
demonstrated by this triptych from three frames of the 35
movie negative (you may need to scroll the large version.)
Note that the two diamond rings are exactly opposite one
another. This proves there was no North or South
displacement from out location with respect to the center of
the moon's disk as it transgressed across the sun. You can
always figure out how much you are off the centerline with a
framing pair of contact shots like this. If a line between
the diamonds goes below the center of the moon, you were
South of the centerline, vice versa in the opposite
case.
One final word before
moving on -- this center image is a typical example of a
well exposed normal photograph of the corona. If you now
compare it with the naked-eye view taken with the SL66, you
can see at once how inadequate any single image is in
recording the shape of a corona. It is made rounder than the
reality of our eye's view, and inner parts wash out into
overexposed pure white, while outer portions are invisible,
too dark to have been picked up on the film. Wish you could
have been with us to see this all, and share in one of the
greatest adventures of my
life!
1974
- When
an accurate path for the June 20th total eclipse was
calculated, many of us were wondering what the blazes we
were going to do to get a decent look at this one. Yes, the
low sun angle assured a wide path, but look at where it was:
out over the Indian Ocean, mostly, hitting land over two
tiny uninhabited islands, and just brushing over the SW tip
of Australia. Gleep. A few enterprising souls decided to put
together the first public jet plane observation trip. Horst
Engel, of VIP
Travel in CA, came
up with the plan, with the help of a veteran eclipse chaser
and astronomy professor (and former department head at
Augustana), Harry Nelson. I saw their small ad in
Sky
& Telescope and
sent off a letter to find out the details.
I liked what I got
back, and thought this seemed perhaps the least risky way to
snag totality. For air viewing, all the seats had been
removed from the Ansett 727 jet on the left side. Only half
a planeload of passengers would fly the short trip, and they
would set up their equipment by these windows. I knew a
plane would be less unstable than a ship, but wanted to be
sure, as I intended to take many exposures with my latest
radial gradient ND filter (more below), which needed a slow
shutter speed. So I built a very fast tele lens (f/5 for
600mm) from Jaegers parts, and went to Connecticut to search
out the wonderful Ken-Labs people, who made gyro stabilizers
for camera equipment.
I'll skip the details
here, with a deeply felt "thank
you" to the many
people who helped me to get ready for the tricky challenge.
I became good friends with a lot of the other travelers on
that trip, although none as close as with Harry and Horst,
who I later joined as a member of the adventurous
Eclipse-Chaser's Club (it eventually disbanded in the
mid-80's). As you can see from the above photo (which got
reprinted quite a lot back then, for very few other decent
coronal shots from this eclipse existed) we were successful.
By chasing the shadow we experienced about 7 min. 12 sec. of
totality, a bit longer than I'd seen in 1973. Immediately
after totality I caught this shot of some of the clutter
near me on board, a jungle of tripods, cameras, and small
telescopes.
I've
seen other snapshots of many of us set up on that flight --
phew! It was certainly memorable, and my equipment behaved
smoothly, showing many weeks of preparation were not wasted.
That's the big, fast tele lens you see here in the center,
with a heavy 250 exposure back Topcon attached (the gyros
were towards the window and can't be seen here). The cabin
coloration is yellow-green-gray, due to the narrow diamond
ring's weird light illuminating the plane at the time. The
pilot managed to handle the navigating extremely well, as
the duration proved (we were actually just a little south of
the centerline). Harry sat up front with him, announcing
timings and other info over the plane's intercom. I also
gave him my stopwatch for timing totality for the rest of
us. Harry also was a big help in many other ways with all my
equipment's needs. He was an excellent friend to observe
with (we saw several more together, like 1977, below.)
As
the diamond ring ended totality, the plane turned very
slightly right (do they say "starboard"?) and leveled off.
We could now watch an astonishing sight: the huge rounded
shadow (umbra) of the moon was spectacularly visible on the
cloud-deck below us (all land and ship based observations
were clouded out), as it sped off supersonically. Wow! I
scrambled for my 20mm lens, to take this very wide angle
view of this amazing, ominous charcoal blue "t-h-i-n-g", a
menacing darkness that dwarfed our plane, and made us all
feel like teensy gnats floating just above the hemline of a
silent, fleet-footed giant (can't you just sense that from
this shot?). In some ways, this was as dramatic as the
eclipse itself. But totality was subdued by the small
windows. It felt more like watching it on TV than actually
being there. I've only witnessed totality one more time
(1979) from a plane for that reason. Yes, the shadow IS
amazing. But the main show is compromised, even when you've
been kindly given the best window on the plane (which was
still none too wonderful -- three layers of plastic -- ick,
indeed).
Those
original special filters had a lot of problems with them
(Jon
Kern's are
SO
much better!), and my first few were none too good. After
scanning the image to the left yesterday, I had to remove an
annoying mess of tiny hairs and other airborne dust specks
that were static-attracted by the filter's acetate base
aboard a low-humidity jet, and showed up on every print,
grumble, grumble... I did my best to make the view you can
see here, long before Macs and Photoshop and digital imaging
were even a dream. And you can see that the innermost corona
came out much too dark, while the middle portion was
rendered way too bright (oops). Kinda ugly, ain't it? But it
does show the rather complex, boomerang shaped (Australian?
;^) corona we experienced late that morning, a couple of
hundred miles west of Perth, from whence we'd departed, only
to return to a few hours later, on a "journey
to nowhere." All
the same, I wish you could have been there...
In
preparing this report for you, I wondered if I might come up
with one more image, combining the tediously cleaned
rad-grad photo just above, with the very decent image
further above, which I took with a single 1/8th sec.
exposure. Took a lot of Wacom to "interpolate the rest."
That first shot was made with twice as high a resolution
(2-1/4" Rollei with a Celestron 1250mm telescope, my
"back-up" rig), and shows the corona better where the above
fails to, and vice-versa. So here for the first time
(probably anywhere) is a final composite image that gives
you a good look at the lovely corona that brisk winter's day
(June in Australia), as it appeared to the eyes of those of
us lucky to be on board. It may not be as sharp or free of
flaws as some of the later images you see here, but it was
worth some extra work to document a totality few people ever
saw.
(Note:
thanx to a couple of you who wrote to ask that we post this
eclipse here next, as you remembered being there with us.
Thank you, and enjoy!)
1976
- And
now here's a unique "total eclipse" of a rather surprising
kind, one that took place in April of 1976. We've created a
special page for this seldom remembered astronomical event.
To see the images and read the full report on a very rare
example
of totality, just click here.
(Then don't forget to come back, since we've got many more
gorgeous solar eclipses to show you!)
1977
- This
October totality had to be observed from the deck of another
ship, the SS Fairsea, in the middle Pacific Ocean, several
hundred miles due west of Panama. You can see me nearly all
set for the "show" in the photo to the left. Lois Nelson, an
experienced eclipse chasing pal, is wisely shading me with
my umbrella, while I'm occupied with equipment, although I
did get a slight burn that afternoon. To the left of Lois is
Steve Greenberg, one of the more knowledgeable
"coronaphiles" I met at many eclipses in the 70's-80's. I'm
grinning for the ship's photographer, in front of a
windbreaker the ship's carpenter built and painted for me
(the wind conditions were intense.) This was thanks to Harry
Nelson, Lois's dad, who was the head of our little
"Eclipse
Chaser's Club",
during our mini expeditions from 1974 to 84 (more above, for
1974). He always looked out for me, as I took the most
ambitious pix for the club, but I was often an
"absent-minded professor," who needed help. Harry somehow
got the breaker constructed the night before.

2nd
Contact begins..
|
..as
the clouds leave
|
As totality approached, we counted several clusters of
low-lying cumulus clouds occasionally blocking our view. The
final group moved off at 2nd contact (shades of 1963!) as
you will see in the two consecutive views just above. The
moon presented a very deep valley at the spot where the
sun's last slice of chromosphere could shine forth,
producing an unusually long diamond ring of over 11 seconds!
(Extra:
see more about the moon's limb right
HERE.)
Sky conditions were excellent, and I got off about a dozen
frames before another swiftly moving clouds took it all away
again a minute later.
This
was the first corona in which I began to develop the
careful, tedious darkroom method (since the earlier
experiments with a so-called "rad-grad filter" had been
problematic) of compositing four negatives, to get this
near-naked eye view of a near minimum-type corona: streamers
spread out mostly horizontally, and short polar
"plumes/brushes" above and below.
I was limited to the
slowest exposures I could get by being on board a bouncing,
or at least greatly drifting, moving platform (had no choice
this time, so I gave in against my previous rant in 1972,
"Never again!" At least this ship was not quite so filled
with tourists of the "football fan" variety -- the Olympia
had been the true "ship of fools"!) Because of this
limitation, the outer portions of the composite view above
are not so well imaged, even with a careful attempt to fill
in that small weakness when I made the computerized version
for you here. This was also the first eclipse during which I
met Jay Pasachoff, a very well-known eclipse expert and
astronomer, with whom I've just collaborated
on a new image from
the 1998 eclipse you may wish to look at...
