Objects Session Notes
NGC 2674 - Spiral Galaxy (?with Type 1a Supernova 2020eqv) NGC 5157 - Spiral Galaxy with Type 1a SN 2020ees NGC 4567 & NGC 4568 - Spiral Galaxies NGC 4568 - Spiral Galaxy with Type IIb Supernovae 2020fqv NGC 4636 - Elliptical Galaxy, with Type Ia Supernova 2020ue Variable Stars (photometric monitoring) - None Nearby Stars (astrometric monitoring) - None
- Evening session (1.7 hours total). Session ended when clouds rolled in at 23:45
- Main aims of the session was to follow up on earlier supernova observations and acquire images of a selection of deep sky and comet objects - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 2.5°C (min)
(Dew heaters on auto)- CCD Temperature: -20°C (65% av. power) - Notes from 2020-04-24 >>
| NGC 2674 (Hydra) Might still show SN 2020eqv (Type 1a), discovered 2020/03/21.310 Images acquired under bright sky / horizon haze. Image also shows some initial frosting on the CCD or CCD window. Target to be rescheuled in order to get a better image |

| NGC 2674 - Detail SN 2020eqv (Type 1a) (= ASASSN-20dk) discovered 2020/03/21.310 by All Sky Automated Survey for SuperNovae (ASAS-SN) Located 0".0 east and 0".0 north of the center of NGC 2674 (Rochester Supernova site | Discovery image | ) Image below (2020-04-24.892) was taken 34.58 days after discovery of SN 2020eqv Centered close to the nucleus of the host galaxy it is not possible to resolve the SN directly. Without an equivalent pre-SN archival image, it is not possible to identify any brightening of the galaxy that could otherwise potentially confirm the presence of a supernovae. Calibrated magnitude of host galaxy + possible SN in image below is +14.91 This might be compared with the magnitude of galaxy in a later post-SN image (Comparison with catalog magnitude is inclusive : NGC 2674 catalog mag +14.9 , NGC 2674 / PGC 24785 catalog mag +15.8) |
