Objects Session Notes
Nova Per 2020 - Nova (V1112 Per, AT2020abap) Nova Cas 2021 - Nova (V1405 Cas) TBA Variable Stars (photometric monitoring) - None Nearby Stars (astrometric monitoring) - 61 Cyg
- Night session (5.6 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: 2°C (min) - CCD Temperature: -20°C - Notes from 2021-04-24 >> [ Local Files >> ] -

Nova Cas 2021 (Cassiopeia) Nova in Cassiopeia discovered 2021-03-18.4236, by Yuji Nakamura (Japan) Magnitude at discovery +9.6 (unfiltered CCD) AT2021hkn (Type: Nova) reported by 2021/03/30.055 UT by Gaia Alias: Gaia21bpe, AT2021hkn, V1405 Cas |
Nova Cas 2021 / AT2021hkn - 2021-04-24 (T+37.5d) Image below (2021-04-24.968) was taken 37.5 days after after discovery of Nova Nova is shown by white cross hairs. Measured magnitude +7.99 Note: star object is saturated and shows some blooming, mag is probably underestimated (linked with Detection Threshold = 50) |
