Weather is good enough...for now.
I see the same thing that Shawn sees at the coord's Arne passed on:
18:59:32.95 +42:24:12.2 J2000
Using GSC 3127-1780 (approx mag 13.2).... V358 Lyr is mag 16.0
unfiltered. I can continue unfiltered time series for another three
hours (too low)...or cirrus clouds cut me off.
I'm also running a BVRI repeated sequence on the other scope.
