Dear All, 

CLAS12 is steadily taking data with I=45nA at the beam energy 10.6 GeV. 
We accept 16 kHz triggers with 93% lifetime. 

The mayor trigger are: 
- Electron trigger - 10 kHz 
- Forward tagger trigger - 3.5 kHz 
- Muon trigger - 2.3 kHz 

We added random Faraday trigger with rate around 300 Hz. 
DAQ is performing very good with occasionally minor problems. 

We will take data up to 08:00AM Monday . No changes are expected in the trigger or 
data taking conditions. By this reason the RC meting is cancelled today . 

The accelerator folks will perform beam study during day shift on Monday . 
We will resume data taking after 4:00PM. 

Let me or PDL (Eugene) know if you need control access on Monday . 

Have a nice week end, 
Valery
