APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday October 10, 2026 (SJD 61324) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Sat 10 Oct 2026 61324 dark (10.2 h) plus 0.2 h for 12 deg design ---- Observing Summary ---- A cloudy night, including a few waves of light rain. The satellite imagery hinted at potential sucker holes in the clouds opening up enough to try to open during the last couple hours of the night, but nothing opened up to justify an opening attempt. In addition, one wave of rain after midnight was not accompanied by any radar signatures, so these clouds weren't to be tested too much. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive.

Too coudy to open right now and by the looks of the radar and satellite imagery it's only going to get worse. Humidity almost to 80%, but it's the current clouds and the incoming more threatening clouds that are the biggest issue right now. 08:40Z - We've had a couple bouts of light rain so far. The second wave about an hour or so ago occurred without the radar indicating any precip over us, so that's again cause to be extra careful with these clouds. Wind has picked up to >30 mph consistent with the forecast, but humidity is acceptable. 11:16Z - Called it a night. FPS powered-off. Positioners are home/folded.
