TO CommentsClear initially however clouds dominated the second half of the night.


RA CommentsNight devoted to science. Sky mostly clear at sunset. Took L/V skyflats. Severe problems with LRS-B channel. Forced to use "LRS2-R only" targets for observing selection. Heavy, fast-moving clouds the last third of the night.
