    Shift begins with production runs (2281, 21188) in progress. HAPPEX run 31377 is in progress, started at 13:16.

    The Compton cavity isn't locking; experts are working on it.

    16:05---Take target NMR sweep before starting the next set of runs.

    16:11---Resume production running. 

    	2282	21189
	2283	21190
	2284	21191
	2285	21192

    17:51---Started new HAPPEX run, 31378.

    18:18---Bryan re-enabled the RHRS edtm during the last few minutes of run 21192.

    18:21---Resume production running. 

    	2286	21193

    18:53---Ended runs (2286, 21193). Changed the RHRS momentum to 2.225 GeV/c from 2.25 GeV/c.

    19:19---R-HRS seems to have stabilized. Resume production running. 

    	2287	21194
	2288	21195

    20:24---Take target NMR sweep before starting the next set of runs. Resume production running. 

    	2289	21196
	2290	21197
	2291	21198

    21:49---A. Camsonne has given up on restoring the Compton for tonight. See HALog entry 273731 for his summary of the evening.

    21:55---Beam lost due to RF problem; should be back soon. Runs (2291, 21198) are left running. Beam restored at 22:11. Gone again 22:16; back at 22:20.

    22:26---Started new HAPPEX run, 31379 Continuing production running. 

    	2292	21199
	2293	21200
	2294	21201
	2295	21202

    Shift ends with runs (2295, 21202) in progress, and HAPPEX run 31379 in progress. There is not a Compton run in progress due to the trouble with the laser.
