Subject: 2.5m obslog 20250615 (SJD 60842) From: doravetz@apo.nmsu.edu Date: Mon, 16 Jun 2025 11:04:55 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday June 15, 2025 (SJD 60842) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Sun 15 Jun 2025 60842 dark until 05:52 (2.3 h), then bright (6.0 h, w/ 1.3 h for 8 deg design) ---- Observing Summary ---- The night was lost to wind, clouds, and radar returns. Tonight did not go according to plan with respect to the weather forecast. Instead of a clear night, an outflow to the east produced strong winds with 40 mph gusts early in the night and then clouds and associated radar returns thereafter. By ~10:15Z when the radar returns had finally cleared, the sky was actually cloudier with higher-level clouds than it had been with the sparser, lower-level, more threatening clouds that preceded them. The clouds mostly cleared out by 10:50Z but it was already into twilight at that point. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive, but alertsActor had a stale apogee.ditherIndexer alert, so I restarted alerts.

I did test an FVC loop to check for any of the errors I saw last night about "no light seen in images." I loaded a design from the queue, executed the configuration, and then ran an FVC loop. The FVC loop completed and there were no errors. 10:07Z - Looked like there may have been a big enough sucker hole to open once the radar returns mostly cleared, but now it's cloudy again. Oh well. 10:57Z - Well the sky is clear now, but it's already twilight. Called it a night. FPS powered-off. Positioners are home/folded.
