Weather
It was the very best night of the summer so far. Virtually could-free, fairly haze-free, with steady seeing and light wind. Temp was 72 > 65F, humiditiy around 65%
Rig 1: WR134,135, & 137
This was likely the last night I could get a full set of three spectra for each target. Due to a screw-up I wasted about 30 minutes getting the third wr135 spectrum – so never did get the third WR137. I still cannot figure out why spectral traces are skewed in one direction. Tonight’s data and those from the most recent previous night both await new flat fields. Not 100% sure they’re needed – but would not hurt. I tried running the camera at -15C but it just would not go that low, so I ended up getting -14C bias and darks. Not even sure the camera was at -14C throughout the night.
Rig #2: V1101 Aql
A newer target from Joe Patterson, did a sequence of 1-minute exposures. Also got new flats – use them for tonight’s and the most recent previous evening’s images (also of V1101 Aql.
