Session Notes

NGC 3254 - Spiral Galaxy with Type Ia Supernova 2019np 46P/Wirtanen - Comet To be added     Photometric Monitoring - Variables   - NV Ori,  CN Orio     Astrometric Monitoring - Nearby Stars  - None

- Short evening session,  Duration 1.1hr Session operated in  fully automated mode, and monitored over remote connection. After a promising start cloud rapidly rolled in and brought the session to an end. - Main aim of the session was general observing with mix of variable stars, nearby stars, comets and deep sky targets.      - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  4°C (min) - CCD Temperature:  -20°C  (70% av. power) - Notes from 2019-03-09 >>
