Last night we got CW beam in the Hall. The beam centering with hole target was not successful, but the beam was on the target without the raster on. The harp scans did not work (they don't move). It could be some ioc issue - experts are working on it. We also took some runs to tune the SOS quad with optics target and to check trigger efficiencies.  MCC is currently working on RF separation to deliver beam to A and D. Once this is complete we will do a quick beam centering check, followed by BPM/Harp runs (if Harp works).  We plan to cooldown the target tomorrow morning and install sieve slit to start optics calibrations runs for R-HRS.
