APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday June 25, 2026 (SJD 61217) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Thu 25 Jun 2026 61217 bright until 09:04 (6.8 h, w/ 1.3 h for 8 deg design), then dark (1.5 h) ---- Observing Summary ---- Very similar weather pattern as last night with many waves of light rain until about 08:30Z. During the first half of the night the hourly forecasts were suggesting a period of 1+ hours of clearing skies occurring during the middle of the second half of the night and there was eventually a brief sucker hole at ~10:00Z, but about 20 minutes later clouds were back, though less threatening looking despite radar returns still associated with them. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive.

The radar returns are fairly widespread and still coming from the west like last night. 07:35Z - Another wave of light rain. Lasts long enough to wet the sidewalks, but not really soak into the dirt. 08:15Z - Still cloudy. The virga in the basin when the moonlight breaks through for a minute or two is a pretty sight. 09:45Z - Looks like a sucker hole should be coming, but I think it will be relatively short-lived because I can see the clouds behind it. 10:45Z - Called it a night. Clouds are back. FPS powered-off. Positioners are home/folded. APOGEE morning cals started. ---- Mirror Numbers ---- Saved new nominal MIGs since a couple of batteries were replaced this afternoon. With shutdown being so close, these should be plenty good enough and then we'll need new ones post-shutdown anyway.
