Issue with ARCoIRIS calibration lamps from the previous night of engineering was fixed during the day before we started.
Pointing model generated during previous engineering night worked great - very repeatable pointing all night.
All systems were operating smoothly - ARCoIRIS, TCS, etc. Thank you Hernan, Claudio, and David for your help.
With the thin clouds during middle of night we were only able to observe a small number of our
brightest targets (J~14 just visible with slitviewer; mostly stuck to J~11-13 targets).
I have more general comments on ARCoIRIS that I will save for the EOR.
