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 - 2021-04-14 (T+26.7d) Image below (2021-04-13.105) was taken 26.7 days after after discovery of Nova Nova is shown by white cross hairs. Measured magnitude +8.27 Note: star object is saturated and shows significant blooming, mag is likely to be underestimated (linked with Detection Threshold = 50) |
