It 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..?

Okay 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?

Ruth, no I had both feet firmly on the ground in my backyard when I took that shot with a telephoto zoom. Careful cropping makes it appear to be taken from a plane also.

Lacunosus and Asperitas sometimes get confused.. They can co-exist during an event. I caught the bully wind pushing around some lacunosus behind my back, but I don’t stay still long and caught the wind rolling the cloud there low right of center

I almost missed this one too Ruth. I swear, not a few days after President Musk started laying off air traffic controllers, this happened! Yep, we got arcs colliding into each other . Look carefully!! From the bottom up, 22 degree halo, upper tangent arc, Perry Arc, then BAM! the circum Zenith arc gets run over by the 44(?) degree arc..Thank goodness no body got hurt,.
