[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.
