STATE of H1: Observing

INCOMING OPERATOR: Corey

SHIFT SUMMARY:  Started locked and then lost it after 5 hours due to a glitch that can be seen in ASC CSOFT/CHARD. After trouble relocking (constant OMC warnings from verbal alarms before lockloss), I did an initial alignment. Leaving it locked for an hour at 113 Mpc.
