We need a little more time to replace other GEO phone. * MIR: HR of SRM cleaning is going on yesterday and today, HR of SR3 is the next. * DGS: RFM network is available for both X and Y arm. * CAM: k1cam0 was recovered. * OMC: It was found that the beam is blocked by Type C OSEM. We need some modifications at the frame. ==== Work plan (*:responsible person) ==== * COM: Alignment of ITMY today. * Type A: Releasing ETMY lock.
