Session Notes

38P/Stephan-Oterma - Comet     NGC 2251 - Open Cluster (H VIII-3)     UGC 118 & PGC 212483 - Spiral Galaxies with Supernova AT2019B     Photometric Monitoring - Variables   - None     Astrometric Monitoring - Nearby Stars  - None

- Evening Session,  Duration 3.6 hr Session operated in fully automated mode, but monitored over remote connection.  - Main aim of the session was to take advantage of some clear evening skies before cloud was forecast to roll in at 22:00 or 23:00 hrs     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  4.0°C (minimum)  - CCD Temperature:  -20°C (68% av. power) - Notes from 2019-02-06 >>

UGC 118 & PGC 212483 - Spiral Galaxies with Supernova 2019B

UGC 118 / NGC 42  & PGC 212483 with SN 2019B  (Pegasus) SN 2019B (Type: II) discovered 2019/01/01.250 by All Sky Automated Survey for SuperNovae (ASAS-SN) Discovery Magnitude 17.6 (g-Sloan Filter)  (Rochester Supernova site |  Discovery Image  ) The Rochester site implies that the SN might be associated with UGC 118, but another strong possibility is that it is associated with the closer lying PGC 212483 ( TNS 2019B )

SN 2019B - 2019-02-06 (T+36.6d) Image below (2019-02-06.822) was taken 36.6 days after discovery Position of supernova (faint) is indicated.
