[18:49:17] SESSION START
[18:49:17] obs arrival Percy
[18:49:17] obs arrival Nick
[18:49:17] Active instrument: PICSI2
[18:49:35] Arrived at 0620
[18:50:00] Instrument change PICSARR2 --> PICSI2
[18:51:27] Attempting to point with Venus, but it is much too bright. Additionally, there do appear to be skycover is 42%, we may not be able to see anything until the clouds clear
[20:15:15] The target is in view. Beginning capture
[20:39:43] Beginning second capture of HD 147084
[20:59:33] Beginning third  capture of HD 147084
[21:20:51] Changed filter to g
[21:21:02] Beginning fourth capture of HD 147084
[21:48:00] Slewing to Alpha Lac
[21:50:08] Adjusted focus to 1840.3
[21:50:36] Beginning capture of Alpha Lac
[21:55:13] Received an error message from the DDC controller
[21:56:47] Restarting alpha lac captures
[22:07:27] alpha lac captures complete
[22:07:51] Slewing to GRW +708247
[22:40:47] Used the GAIA script to confirm thtat identity of the target
[22:40:55] Beginning captures of GRW +708247
[00:03:51] Cancelled captures of GRW +708247
[00:04:30] Slewed to Saturn, and beginning captures
[00:07:24] Beginning u filter capture of Saturn
[00:23:33] Complete
[00:25:38] Beginning g filter capture of Saturn
[00:44:04] Complete
[00:44:22] Beginning r capture of Saturn
[01:03:48] Complete
[01:04:13] Beginning z capture of Saturn
[01:18:55] Capture failed. Leaving sharpcap and reconnecting the ddc controller
[01:20:29] Restarting z capture of Saturn
[01:34:14] Captures of Saturn complete
[01:35:26] Slewing to GRW +708247
[01:39:04] GRW +708247 acquired, beginning capture
[01:53:44] Will try to stick it out through this capture - but sky cover is expected to shoot up. If it gets particularly bad, I'll cancel the capture and call it a night.
[02:34:59] Clouds have rolled in. The target has been completely obscured. Will wait it out until 0245 to see if it clears
[02:50:25] Cleared up.
[03:36:54] Capture stopped due to an error: "DDC-Unit took toot long to respond. Please reconnect the DDC Controller
[03:38:12] Leaving sharpcap and reconnecting ddc controller, then moving on to the next target.
[03:39:08] Obs arrival Braydn
[03:39:19] @ 0130
[03:44:47] Slewed to Saturn
[03:46:07] Beginning u filter capture of Saturn
[03:54:58] Complete
[04:09:06] Began r filter capture of Saturn at 0358
[04:09:39] Slewing to GRW +708247
[04:14:30] Beginning capture of  GRW +708247
[05:35:58] Capture cancelled 36 minutes from completion. This is something that must be addressed.
[05:38:56] Seeing that there is only 23 minutes left of the shift, we'll take the phi cas capture and then begin shutdown
[05:40:16] Beginning phi cas filter
[05:43:02] *capture
[05:47:56] phi cas capture complete
[05:48:07] Beginning shutdown procedure
[05:55:04] Shutdown complete.
