This is a good event which should be fairly easy. Alt=46 Az=108 in East. The RUWE=1.85 which is a little high, so the path might vary from prediction. Kirk is on the southern limit, I'm closer to the centerline which goes roughly over Costco in an east-west direction. Does not pass near Karl.
max Duration=1.1s

We had clear calm skies, but with a near full moon. Still, the star was easy at 4x and probably do-able at 2x.
I observed from home, at 4x. Visually, live, I saw a dip lasting about 1/2s but it did not completely disappear. Otherwise the seeing was steady and good, so the dip stood out at least in my mind.
Start: 5:36:28UT End: 5:39:42UT for recording
PyOTE found an event, about 1.7s after prediction. The drop was supposed to be 2.3 magnitudes, but the actual event was quite a bit less, only 0.55 magnitudes. I suspect a binary star where only one component was occulted. Kirk found a very similar shallow drop of 0.6 magnitudes. The full duration was supposed to be 1.1s, mine was 0.72s and Kirk's at home was 0.53s, suggesting neither of us were near the centerline. Perhaps a bit more reason if it were binary, to have one component of a tight binary be missed.

Observed from home. For Floirac, Friday the 10th, I got a .5338 sec event from home, 4x.
Used a nest of static apertures, found size 2.4 gave best results. About 2 sec. later than predicted.
