Night Log 2012-09-17

SA: Tim
SO: Fred
Others: benoit, kelley, charl


thick high clouds in the first half of the night gave way to clear skies and high wind in the second half. humidity spiked during morning twilight as a harbinger of ridge cloud to come tomorrow night. temperature dropped almost 13 C over the course of the night. seeing was good at times, but high winds prevented an alignment good enough to take advantage of it. IQ was so dire at the end that CAL_SPST and a P4 were the only viable options. ultimately completed 5 blocks and rejected two others. fabry-perot was again shown to be compromised by software bugs.
