That’s weird, that’s the second time lately that hosting site has randomly deleted a set of my images (never mind that Discourse is random whether it embeds them or not). I won’t try reupping them all to Imgur (which is flakey for me) but here’s the best of the group, which shows both red and green patches.
(That is from my phone’s “night mode”, which a check of the EXIF shows to be ISO-16896, 1/6s.)
