keyword=BPM's at start of Day ShiftNoticed beam positons a little unstable at return of beam, but not as bad as I had originally thought. The scale for the BPM's is -1 to 1, so the excersions were withing the 0.2mm dolerance. Nevertheless, we called MCC to make sure they were keeping an eye on it in accordance with OPS ELOG entry 1398488 which seemed to have had a positive effect over the Owl Shift. In this note, they indicate that turning the FFB on after reaching the desired current seems to help the beam position stability.
