Smithsonian photographer Carl Hansen describes his experiences photographing an eclipse of the sun. Hansen is presently chief of the Smithsonian Office of Printing and Photographic Services Branch at the National Museum of Natural History
On July 11, 1991, I had my first opportunity to view and photograph a total solar eclipse. At the time I was assigned to the Smithsonian Institution's Tropical Research Institute in Panama, Central America as the Chief of Photography.
The day before the eclipse was scheduled to occur I drove out to the savanna region hoping to find a hilltop to camp on for the evening. I wanted to be in the Savanna (dry) region because I thought that would be the most likely region to be free of cloud cover.
We located the perfect hilltop quite a few miles west of the town of Las Tablas. The property owner gave us permission to camp on the rocky hilltop though he thought we were a bit strange, wanting to camp in such a dry exposed spot.
The next morning we were joined on our hilltop by the property owner's son and his friends as well as several other Panamanians who were driving by and decided we had picked an ideal spot to view the eclipse.
A total eclipse is truely a multisensual experience. You don't just view it but you hear, smell and feel it.
As the time for the eclipse approached I was disappointed because there was a fairly heavy cloud cover that was moving rapidly to obscure our view. We could still view the moon gradually eating away at the sun but we feared that the cloud cover at totality would be too thick to get good photographs. However our luck changed, just before totality the clouds cleared completely and we had an unobstructed view (one of the few world wide and the only place in Panama) of the eclipse.
But the experience began before totatity. First the sky started darkening. As the false evening progressed birds began flying to roost and started their evening chorus. In the fields below us the cattle gathered up and started heading in from the pasture to the feeding barn. Next the air took on a different fragrance and some plants closed up their blooms. As totality arrived it got dark as the darkest night, because there was no moonlight to compensate. And the temperature dropped noticeably. In a matter of minutes it went from that hot, dry sunny July day to a cool, fresh, very dark night. An incredible experience!
Totality lasted only a few minutes during which red solar flares were distinctly visible around the edges of the blocking moon. Then the whole scenario reversed itself. It got lighter and warmer. The birds stopped singing and returned to feeding sites. The cattle left the barn yard and returned to the pastures. We all gushed excitedly and chattered on amongst ourselves about what an incredible experience we had shared.
The photograph at the top of this page shows the flaring effect produced by totality.
