Some of the best pictures I got from Monday's solar
#Eclipse. 3 of them were taken using an app called SunSketcher, a crowd sourced citizen science study of the shape of the sun. Wait, isn't the sun a sphere? Not quite, like the Earth, it rotates and is oblate. But exactly how oblate, and thus its exact shape is very hard to measure. By photographing the eclipse, and comparing it's shape to the sun's using Bailey's beads allows more precise measurements. Wicked cool and glad to help.
