APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday September 15, 2026 (SJD 61299) ---- Observing Team ---- Dmitry Bizyaev ---- Observing Plan ---- Tue 15 Sep 2026 61299 0.26 02:02 02:17 11:39 18:54 04:17 --- dark ( 9.4 h) plus 1.0 h for 8 deg design ---- Observing Summary ---- The entire night was lost to cloudy sky, nearby radars, borderline humidity and rain. ---- Engineering Issues ---- In the morning we had a few waves of decent rain in combination with strong wind gusts from the South. I inspected the enclosure's ceiling trying to find water drops. At the center and around the telescope no any water drops can be seen. There is one spot at the SE corner where the roof leaks and water goes to the walls and then drops to the floor at the SE corner of the enclosure, but this spot is far away from the telescope structure. I also tried to look at the ceiling with Hg bright lamps on with the same result. ---- Observing Log ---- Afternoon ========= All systems found working as expected.
