- Remote participants by eZuce: Miyoki
- Report of work (*:responsible person)
- Alignment and ETMY: *Enomoto
- Photo sensor noise was improved on Thursday and checked on Friday. We confirmed the noise becomes better.
- Sampling model of RT model was changed from 16kHz to 2kHz to reduce 10min period glitch.
- Camera: Inoue, Haino, Yokozawa, Cory, Binhua
- ETMY Camera was broken by taking too many photos. Camera will be replaced.
- ITMY camera is being set to look at BS.
- BS PD will be replaced by Yokozawa.
- CRY: mirror temperature ~110K.
- The satellite amplifier has an oscillation for photo sensors at low temperature. Satellite amplifiers which will be used for photo sensors at low temperature should be modified.
