We didn't get much beam since yesterday,<br>
MCC is still working on resolving Accelerator related issues( RF <br>
separator, RF zone 1L03).<br>
I think there is no much to discuss for today.<br>
Instead will be good if we work on the analysis of the special runs <br>
(random, packed data, Lumi scans),<br>
and in tomorrow's RC meeting discuss what decisions we should make in <br>
terms of trigger/bit packing and the beam current.<br>
