| 1696 | 01:07-01:07, 06:42-06:42 | 00:00 | Took out 36-6 for LTRSE. At 06:42 UT I took out 55-3 for LTRSE. | |
| 4459 | 02:48-03:00 | 00:12 | Sent a Go next trajectory with dome and structure checked. The dome did not move from CCAS to the correct azimuth. Error and details in PR. | For good measure brought down the servers and tcs Gui and brought them back up. This fixed it. |
| 4458 | 03:30-11:30 | 08:00 | LRS2 crashes when taking an exposure with the PFIP shutter. | Called: Jason, Niv, Randy Jason and Niv could not be reached. Randy suggested restarting PFIP, power cycling the PFIP "ALL". None of these seemed to work. |

| TO Comments | All clear till a sudden change in temperature and wind direction (temp dropped 7C in 10 mins and wind went from 275 to 390). The 1 micron dust also jumped from 24k to 136k in less than 5 mins. Closed as fast as possible. Looked at hourly forecast and the temp is supposed to drop close to the dew point so I left lights and AHUs running with the chiller off. |

| RA Comments | Problems with the PFIP shutter tonight stopped engineering effort. |
