2012-10-11 (2012B-0057): 7 hrs used, 3 hrs lost (Weather), 0.5 hrs lost (Telescope control problem) Comment: 7:38 pm alarm sounded. Selsyns read 2:38 hrs RA, 19:39 deg Dec. Slewing when got alarm. No indicators on panels -- ack'd alarm to shut it off. Power on, oil pumps on. RA on drive rack lit, pushed to reset. No bearing limit lights. Slewed OK using Checklist red binder, then next slew caused alarm again. Killed GSC chart up when both alarms occurred, and had no more alarms until 1:24 am. This alarm identical to others, except no alarm downstairs on drive rack. Might have been caused by strong wind gusts.
