<pre>
Since last night(8:30PM), we continue to data collection with almost 20uA at optics target through both LHRS and RHRS.
So far (till this morning 6:30AM), we have 4hrs run although we had experienced some of troubles (LHRS Dipole trips[twice]/LeftDAQ crash[several times]/...)

The current plan I understand is...
(1) 8hrs more to go with sieve/20uA/optics target (LQ1=662.11A, RQ1=153.36A)
(2) Three special runs(1hr/run) with sieve/20uA/optics target 
  2-a) RQ1(+5% increased current)(=167.74A)
  2-b) RQ1 off(=0A)
  2-c) LQ1 nominal(827.64A))
(3) Sieve(s) out / Delta Scan with LH2 (3-4hrs)
anything I missed ??

PS: We will have a 4:00PM meeting at the usual place for discussing upcoming plan.
