31. Comments (During Observations) :
19:22 : Starte settings.
19:41 : Power equilised on 1154-350 @ 300 counts.
19:44 : Phasing done on 1154-350.

19:47 : '/odisk/gtac/cmd/jroy/24_022_3jun.cmd' command file started.
23:28 : Stopped command file duo to internal data copy on node34.
Therefore  halt the GSB and restart without changing GSB setting.
23:33 : Started command following command file in which phasing is done on 1822-096.
        '/odisk/gtac/cmd/jroy/24_022_3jun.1.cmd'

07:15 : Buffer loss in GSB data. Stopped GSB Data acquisition.
07:20 : astro8 slowed down. taking long time to respond user commands.
        gave reboot to astro8 machine.
07:40 : W-arm power failure.

07:45 : Closed observation session.
