Objects Session Notes
C/2020 T2 (Palomar) - Comet Nova Per 2020 - Nova (V1112 Per, AT2020abap) AT 2021kmb - Transient (Attempt) NGC 3310 - Spiral Galaxy (Herschel IV-60) with Type II Supernova 2021gmj NGC 4165 - Spiral Galaxy with Type II Supernova 2021gno NGC 5018 - Elliptical Galaxy with Type Ia Supernova 2021fxy UGC 6930 - Spiral Galaxy with Type Ia Supernova 2020rcq UGC 8426 - Spiral Galaxy with Transient AT 2021knq Variable Stars (photometric monitoring) - None Nearby Stars (astrometric monitoring) - None
- Night session (2.7 hours) - Main aims of the session were to acquire a selection of variable star, nearby star and comet targets and deep sky targets as cloud allowed - Poor quality skies - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 0.5°C (min) - CCD Temperature: -20°C - Notes from 2021-05-05 >> [ Local Files >> ] -

| AT 2021kmb (Virgo) AT 2021kmb (Type: *) discovered 2021/04/22.146 UT by Pierluigi Catizone Alias: AT2020lrn Discovery Magnitude 10.0 (Clear Filter) (Rochester Supernova site ) |
| AT 2021kmb - 2021-05-06 (T+13.9d) Image below (2021-05-06.019) was taken 13.9 days after discovery of 2021kmb Position of reported transient (not visible) is shown by white cross-hairs No object is evident at the reported position. Transient has seemingly faded (or moved) Given the target's bright discovery mag (10.0) just 13 days before it is wondered if the source object was actually an asteroid, rather than being a star ? Glare at bottom of image is from HIP 68215 (mag 7.1) which lies just outside FOV Target wasn't centered correctly due to a minor issue (notes) |
