Chi found that the Compton laser was turned off since 10:17 yesturday(thurs) morning. This was turned back on by following the Compton instruction pages.

Coda hung once. Although the configuration was set to physl2t, many events were seen in the data that should not have passed the trigger. We restarted coda and this fixed the problem.

Smooth data taking after this with 45deg spin-angle H. Beam max current of 100mA with spin flipping at 75mA. Beam is dumped for a new fill at 70mA, so the spin flipping current threshold may need to be adjusted.

Data is crunching and has been charge'd. Runlist has been updated.
