    We have LED street lights and our driveway is lined with crepe myrtles. Every evening after dark, I can see the grid pattern of the individual LEDs in the shadows on our driveway. It’s trippy when there’s a slight breeze, and all these little “grid shadows” are moving around overlapping each other

        You can make a hole with your fingers and see the patterns of very bright lights above you, stadium lights etc. It’s just a vertical camera obscura. I remember the 90s solar partial eclipse really well because I was riding home from school, the leaves and even the spokes on my bike projected moons everywhere, it was completely magical.

          I watched the one in the late 2010s through the hole in my transit pass lol

          Had glasses and travelled to totality for the last one. It was incredible. Highly tempted to try to make it to europe for the next one

    You can actually use this, or more generally the shadow of a tree on any sunny day to calculate the distance to the sun !

    (Can’t seem to find the video demonstrating it, but I have a feeling it’s from Physics Girl or Up And Atom on youtube)

    It’s uncanny and special for someone to be looking the other way during an eclipse.

    It’s so short and a rare enough even that would make earth a tourist hotspot for extraterrestrials if there ever was interplanetary tourism.

      You only see this during the partial stage of the eclipse, not during totality, which can last a long time.

        I witnessed a partial eclipse, didn’t notice the shadow effect. I might pay attention next time…

      Unless it was an annular eclipse, or it was a total eclipse and they weren’t in the path of totality. Then this is all they would see. Regardless without eclipse glasses you shouldn’t look at either eclipse at all.

        You can glance at the sun but don’t stare at it. Even when it’s only 1% visible, it’s putting out enough light to strain or damage your eyes.

        Though it’s fine to look at the eclipse with naked eyes when it’s total. You can’t really see the cool effect surrounding the moon during totality with the eclipse glasses on because it’s way dimmer than the sun usually is.

        Your eyes will tell you if it’s safe to look. If it’s uncomfortably bright, then you shouldn’t power through that discomfort (and that applies to things other than the sun). If it feels like looking at anything else, then it’s probably fine.

        I witnessed a partial one, with eclipse glasses. Still I didn’t have the time or observational talent to notice the effect on the shadows

            Ah nice! I liked the Lancairs, i got to fly one of them. For working in i think Pipers were my favorite, especially the Malibu. Plenty of space and logical layouts.

            I guess working in the engines was nicer in the Cessnas since there was less baffling and no turbo, less places to drop books and nuts.
