The first observer started taking cal lamps around 18:35 and we focused around 19:08. The Echelle Slitviewer ICC locked up around 19:22 and needed a power cycle to get it working again. 26 mins were lost. At 21:10 my Remark interface went down and simultaneously the observers Remark interface and internet connection appeared to fail. They needed to completely reboot their Mac. I simply was able to exit Remark and restart it (would not reconnect). 5 mins lost. The MC stayed up during this time, although the guider turned off when the observers Remark died. The second set of observers tonight decided that they wanted to use SPIcam instead of GRIM due to the cirrus clouds in the sky. It took me about 10 mins to prep SPIcam for use on such short notice. They ate the time. At 01:05 the cirrus cleared out enough and the 2nd set of observers had me switch instruments back to GRIM. At 01:48, the GRIM ICC crashed and was rebooted. 6 mins lost ------- FAILURE LOG ------- PROG/INST FAILURE MODE TIME S/E/G/D/O TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- UC01/E I/S 19:22 19:48 Echelle Slitview ICC crashed (locked up) and needed to be Hard power cycled (unplugged/ replugged in AC). UC01/E T/S 21:10 21:16 My Remark went down and the observer lost internet connection at the same time. The MC stayed up but I had to exit and restart Remark. The users Remark locked up and computer needed to be rebooted. He was not able to connect to the internet for about 2 more minutes and then things went back to normal.
