Also, the humidity was becoming high. Reopened at 21:18 but had to close again at 23:15 due to humidity. Weather stayed partially cloudy with moderate seeing. We were able to reopen at 03:38 but closed an hour later again due to high humidity. There was insufficient time to wait for the humidity to decrease and hope to reopen as the targets for UW05 were setting. Spicam is still not producing exposures with any data in them. ARCTIC was substituted for Spicam which is working properly, though there is a small amount of condensation on one of the lenses. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- CU02 S I/H 21:18 23:15 SPIcam producing blank (all 0) images.
