GS-2017B-DD-1-141-001	2017-08-28 23:57:44	Conditions are IQAny, borderline CC70/80. We're continuiing despite the marginal conditions as the target is so time sensitive.
GS-2017B-DD-1-141-002	2017-08-29 00:00:48	Spectrum is visible in subtracted exposures, though not without subtraction.
GS-2017B-DD-1-141-016	2017-08-29 00:44:28	Guide loops were briefly opened during this to check if we still had the guide star. We did, so the data should be good. Last exposure taken as were near the elevation limit.
GS-2017B-DD-1-141-025	2017-08-29 00:48:48	15K counts in flat. We took this and the arc with the telescope fixed at the last observed position, so we didn't track into the elevation limit.
GS-2017B-DD-1-141-026	2017-08-29 00:49:13	arc okay
