                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
Wind and dust were problems tonight. Wind and dust kept us closed from
23:40 till 03:40. Mirror should be cleaned soon given the amount of
sustained levels of dust tonight.
20:50 we switched to generator power after brief power loss.
04:10 switched back over to utility.
Mirror covers failed to close in auto mode twice tonight. Closed them in
manual.
