Night Log 2013-01-14

SA: Tim
SO: Siphelo
Others: hitesh, eben


ridge cloud threatened through most of the night with half the night spent at RH > 80. it didn't reach the closure threshold until the last half hour before morning twilight, though. seeing was good for a spell, but otherwise mediocre to poor and highly variable due to strong SE winds.

lost the first block of the night for 2012-2-UW_OTH-001 first to rapidly deteriorating mirror alignment and then to a cable bundle that worked free and vignetted the beam. after that accepted blocks for 2012-1-GU-001, 2012-2-RSA_DC_OTH-001, and 2012-2-RSA_OTH-002 (x2) with rejected blocks for 2012-2-RSA_UKSC_RU_UC_OTH-001 (seeing blew up) and 2012-2-RSA_OTH-002 (humidity spiked).
