===================================================================



EVENTS



00:13  Started new Happex run #31489 and new Compton run #17226.



00:20  We have lowered the beam current to 5uA for runs #3287/#22160 

       to study rates in Veto planes of ND. (Bogdan's and Simon's 

       suggestion)  



00:56  Before runs #3288 and #22161 we changed the beam current back 

       to 9uA. Run #3287 has 2M events.



00:59  In the beginning of production run #3288 (after 4min), left  

       arm coda reported error, saying that ROC5 did not report

       status for more than 15sec. We have killed left arm Coda,

       rebooted ROC5 and TS12, restarted coda and started new run. 

       It seems that Coda is now working again.  



01:26  We did the NMR frequency sweep. New target polarization 

       is 57.5%



01:54  Alexander called and told me that he noticed that comton ROCs 

       seem to stuck during run #17226 and asked me to do "Coda 

       Reboot". And I did it. New run started normally. 



03:50  Kai started new Compton run #17228.



04:34  Started new Happex run #31490.



05:39  We did the NMR frequency sweep. New target polarization is

       57.1%



06:00  We have started new Compton run #17229.
