ParticipantSooo…I went outside to stretch my legs a couple of days ago and I looked up and this is what I saw:
and thats what most Upper Tangent arcs Ive seen, have looked like to me…flat. More of the Parhelic Circle below
That was it . About half hour later I went outside, looked up ..and other show..but with a lower tangent arc(?). flat like the Upper and a lot of lens flare..why it isn’t wise to shoot into the sun.:

ParticipantIt was too windy for a good look at the eclipse last night. Too much dirt in the air. Clear visibility was crap.Still took a peek or two. Tonite a wide Asperitas event took place north of Phoenix with valley wide undulatus coming in from the west..after the sun had set..oh well..but I did get a lunar halo last month, with Mars visiting the twins….the Locust Moon..?

ParticipantOkay for some fun (?) below is the first photo I took of the Upper Tangent Arc and friends. Obviously I was trying to include the rainbow arc(44 degree arc?) on the far rite. Please compare the upper tangent as first photographed to the shot above in my previous post which was near the last shot. I photographed for 11 minutes shooting 24 pics. So you can see the changes and see the placements of contrails across or near the upper tangent arc. Okay ,ive read that the 44degree halo is theoretically a sundog of a sundog..the lite has to be double refracted by those hexagonal ice crystals..So the one parent is a sundog and the other is whatever has hexagonal ice crystals aligned the same way. What other occupant of the 22 degree halo is there besides the sundog..the upper tangent arc,,so can a upper tangent arc have its own halo?, its own superlateral arc..or are we locked into a 44 because it sits on the 22?
