During day time accelerator down time we changed HWP to OUT and made a Rapid Access to reduce microwave attenuation for polarized target (microwave power is frequency dependent).

Data taking throughout the day, evening and night with semi-stable beam at 4.0 nA.

Lost one ECAL HV board (sector 5) during the night, Nathan fixed COMM errors, HV board will need to be replaced

Plan to change HWP from OUT to IN during the day or evening.
Keep NH3 target polarized negative. 
Maybe a good idea not to reverse target polarization because of the maintenance day Wednesday and the fact that we took less data on negative target polarization so far.

We will have a RC meeting today at 2 PM.
