probably but not necessarily - since not all rain reaches the ground.

whether an end of it was definitely grounded or if it could just have been an air bow.

couldn't see the ground where it was. It went into the cloud, which I've not seen before. Well, besides in "artists renderings..."

Oh, yay for rainbows!

it was surprising, but kind of faint anyway. I was just sitting trying to figure out what Tazzy was up to and was kind of looking and... "wow I am imagining some... oh yeah that's a rainbow..."

also

all rainbows are circles, but usually they aren't viewed from sufficient elevation and the horizon intervenes.

silly horizon...
