16:00 Continue taking data at thcm=90.
17:00 Start to do ep measurement.
Change target to empty position.
Change to kin thcm=135.
carbon door to (1.5+3). 6 msr coll. in both Arms.
P_h=0.8188Gev/c, Theta_h=30.806
18:44 ep energy measurement finished. Change target to Carbon.
19:05 Too many RF trips during the carbon pointing data taking.
21:40 Move the 6msr coll. out from both Arms.
23:14 MCC told us they are having RF problem. It will take a few minutes to fix it.
