We continue to take data on LD2 and collecting d(e,e'p) counts at the
Pm=580 MeV/c. Currently, we are shy of the statistics goal, but I was 
suggested by Jay that the beam studies could start a a later time today,
in order for us to collect the full stats on this setting. I chose 10 AM
for the beam studies, so we have two more hours to collect data.

Since yesterday, Hall C got 70 uA! since Hall A was down part of the time and
taking low (1 uA)  beam current. However, accelerator had two separate instances of
the machine dropping from power permit due to PSS fault, which took a couple of hours
to recover from. We were not able to take full advantage of the 70 uA beam. During
owl, the machine struggled to deliver high current and we received ~30 uA, but now
seem to be recovering and getting higher current (~50 uA)

We will not have an RC meeting today.
