Comments = Poker SDI observations stopped during the dusk-time sodium sequence. Probably the computer had done a reboot and was not properly logged in - the watchdog program kept killing the observation program. I attempted a reboot, but it took a couple of hours to complete. (Doing a chkdsk on reboot, perhaps.) Anyway observations restarted around 7:30.
