I did an attempt this evening. Unfortunately, the sky deteriorated rapidly after
sunset. Quite hazy conditions, but stars visible on the photographs and video.

Video (WATEC + 1.8/50 mm) and photo camera registered nothing around the 18:20
UT pass. I had shadow ingress predicted for 50 degrees elevation in the N-NW
near 18:21:00 UT.

If weather cooperates, new attempts tomorrow and the day after tomorrow (when I
should have a good near-zenith pass).
