Our annular eclipse

Postby Rebecca » Tue May 22, 2012 8:40 am

We got to see a solar eclipse that covered 85% of the sun yesterday. The dappled light from trees was absolutely fascinating!
Here are some shots of what we saw:

Oh man, I love eclipses! We should institute a global project to launch a second moon so we could have them more often.
I am sure you have noticed the phenomenon of local "eclipses" when the sun is partially occluded by a cloud or other object. It doesn't create the multiple projected suns, but it does cast that eerie light, with unnaturally hard shadow edges; I assume because the sun's rays are being crudely focused, like a pinhole camera. Of course, there's nothing like the real thing.

nice pictures Rebecca!
I remember the last time we had a total eclipse in India, I was ready with a pinhole and everything.. as well as a little telescope with a filter. and while I was at it, I noticed the patterns caused by the tiny gaps in the trees just like you had posted, and realized you really don't need much tools to see this spectacle.

Matthew, Yes, those beams of tree filtered light focus like thousands of pinhole cameras... for those who don't already know this, dappled light is always sun shaped -- it's those pesky ellipses again!
gpathy, several neighbors had their gear set up as you describe, and apparently failed to notice the projected eclipses on the ground and walls all around us. I brought a large sheet of white plastic and angled it perpendicular to the sun's rays to maximize the beautiful patterns from the dappled light -- they looked up from their rigs and yelled out in excitement. :D
