Ops Eve Shift Summary

TITLE: 07/31 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 151Mpc
INCOMING OPERATOR: TJ
SHIFT SUMMARY: While last night's shift went on without any observing time, tonight was the exact opposite with H1 locked and observing for the duration with steady range. Many aftershocks of yesterday's large earthquake with magnitudes over 5.0 rolled through continuously this evening, but H1 rode through all of these, occasionally entering earthquake mode during some of the larger motion. H1 has now been locked for over 15 hours.

On an operations note, based on TJ's suggestion from his time on last night's owl shift, I've edited the H1_MANAGER node to start an initial alignment instead of immediately calling for assistance if IR is not found during the 'FIND_IR' state. It will call for assistance, however, if an alignment has already been run and IR is still not found. Changes have been loaded and committed to svn.
