Eclipse 2023


Not exactly the perfect ring of fire, but cool nonetheless.  The first pic is right at the time of maximum occlusion.  That's a partial eclipse alright.  The second is the shadow of palm fronds, with the gaps serving as miniature pinholes; the result is a pattern of crescent suns.

The background  looks blue, but it's really a white envelope used as a projection screen for the pinhole.

It looks like my palms have crescent-itus!  Whatever is the cure?  Oh that's right, just wait 45 minutes.  There's a pretty striking pic here of the same phenomenon, from elsewhere.

Remember kids, don't look straight at the Sun, even when the sky looks dim.  Use a sheet of cardboard to make a pinhole camera and keep those retinas intact.

ps, 10/15: APOD shows a pic of an "eclipse tree" with those crescents in the shadow here.
