Upper Tangent Arc

[Alec Jones]

Hi everyone!

It's been very quiet here in the Bolton Halo Triangle these last few days, with little to report. However, I had a nice surprise this afternoon while I was at work, a well defined upper tangent arc and a possible circumscribed 22 degree halo,

The only other recent observation of any interest was my very first moon pillar,

I appreciate that moon pillars are relatively common, but at least this is another phenomenon I can tick off my list!
