| 4056 | 07:30-07:35 | 00:05 | During a move from az 340 to az 117 heard loud clicks on 1 second interval, and during that move heard lots of rapid clicks for about a second around az 240. | |
| 4057 | 08:40-10:30 | 01:50 | From 08:40 until about 10:30 there were frequent 480 VAC problems which prevented all engineering. They started at the following times: 08:40:30, 08:51:02, 09:29:19, 09:49, 09:54:15. 10:01:54, 10:08:44. After 10:08 the power blinked on and off several times. | |
| 4058 | 10:30-10:35 | 00:05 | After a 480 VAC fault it seems impossible to get TCS to communicate with the tracker without restarting dSPACE. | |
| 4059 | 08:35-08:35 | 00:00 | TCS started responding at a snail's pace, but htcs seemed to be clipping along at a normal speed after I closed the TCS gui. | |

| TO Comments | Mirror team: mirror segments behaved very well tonight. We were open during borderline-high 0.3um dust for high priority work-- about 40 minutes. The fan in the UPS on the control room rack sounded off more than usual tonight, and sounded off longer after raising/lowering TO desk. Attempted to find AMSC 1 satellite and failed. |
