• 1730 UT - Experiment started on-time. Formatter/maser delay offset larger than normal (~2.8 us), it seems stable (+-0.05 us) with clkoff values stable. As the proc file does not call maserdelay I was unsure if this is normal. Called Warren and he is out at the telescope having a look if things are working correctly. At this stage it is being left as is. (Tiege)
• 2122 UT - Schedule halted to put correct receiver on axis. Prior to this, the 22 GHz receiver was installed and no valid data would have been recorded. (JMc)
• 2136 UT - First useful data - previous scan not reached in time after Rx change, (JMc)
• 0606 UT - Pressure and temperatures too high - alarms going off. (25 microns Hg, 20K stage at 42K, and 70K stage at 85K) called Mt. Pleasant and Jim is restarting the vacuum pump. (Bryn)
