SNID suggests z ~ 0.06. | | 01:05 | GD71 | standard | Gr11, 13, 16 | 1, 1.5 | 900 | 1.8 | 1.6 | | | 01:24 | AT2021nv | classification | Gr13 | 1.5 | 900 | 1.8 | 1.7 | Pre-max Ia. Known host z = 0.029. Good match with SN2003du at -10d. | | 01:47 | AT2021nu | classification | Gr13 | 1 | 900 | 1.8 | 1.3 | SN Ib/c? H alpha from host consistent with known host z = 0.044. | | 02:08 | AT2021lm | classification | Gr13 | 1 | 900 | 1.7 | 1.0 | SN I? SNID favours Ia at z ~ 0.12. | | 02:30 | Image Analysis | | | | | | 1.0 | | | 02:55 | AT2020adhg (ATLAS20birn) | classification | Gr13 | 1 | 600 | 1.4 | 1.3 | SN Ia past max. H alpha from host implies z = 0.074. | | 03:11 | AT2021ek | classification | Gr13 | 1 | 900 | 1.3 | 1.0 | SLSN-I? Broad features in the blue region (O II?). H alpha from host implies z = 0.193. At this distance, ZTF light curve implies M_g ~ -21 and slowly rising. | | 03:35 | AT2021mj | classification | Gr13 | 1 | 600 | 1.3 | 1.0 | Normal Ia pre-max. z ~ 0.04 from SNID. | | 03:53 | ZTF20acwondx | classification | Gr13 | 1 | 900 | 1.3 | 1.4 | Nuclear transient. z = 0.073 from H alpha and H beta. Consistent with galaxy spectrum? | | 04:16 | AT2021nf | classification | Gr13 | 1 | 900 | 1.1 | 0.8 | SN II. No host redshift, z ~ 0.03 from SNID. | | 04:42 | L745A | standard | Gr11, 13, 16 | 1, 1.5 | 900 | 1.0 | 0.9 | | | 05:05 | SN2021dn | followup | Gr11, 16 | 1 | 1500, 1500 | 1.7 | 0.9 | | | 06:15 | AT2021ab | classification | Gr13 | 1 | 600 | 1.1 | 0.7 | SN Ia around max. z ~ 0.07 from SNID. | | 06:35 | SN2020acat | followup | Gr11, 16 | 1 | 1500, 1500 | | | | | 07:44 | L745A | standard | Gr11, 13, 16 | 1, 1.5 | 900 | 1.3 | 0.9 | | | 08:04 | AT2021mf | classification | Gr13 | 1 | 300 | 1.2 | 0.9 | Ia. z~0.027 from SNID. | | 08:12 | AT2021pl (ZTF21aaahuox) | classification | Gr13 | 1 | 600 | 1.4 | 0.8 | Ia around max. z ~ 0.07 from SNID. | | 08:34 | AT2019aair (ATLAS20bjoz) | classification | Gr13 | 1 | 600 | 1.3 | 0.8 | Blue continuum. z = 0.051 from host lines, consistent with known redshift on NED. | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
