    Shane shut REAL off remotely at about 9:53 PM PDT.   We've been running continuously for a long time and are at 12,552,855 shots on this set of flashlamps.   With light winds, we have not seen much aerosol structure for days so have decided to conserve flashlamps again during the overnight hours or when winds are from the north.
