 UT Target Type Setup Slit Exposure[s] Airmass Seeing["] Notes
 12:53    2020adpg     classification     Gr13     1 300 2.4  Normal Ia around peak, z ~ 0.03
 01:04     2020adhh classification Gr13 1 600 2.1 SN II? H alpha from host at z = 0.022.
 01:22 Image Analysis       ~2 hours lost due to technical difficulties. Systems were restarted.
 03:11 L745A     standard Gr11, 13, 16 1 900 1.2 1.28 
 03:36 2020acpg classification Gr13 1 900 1.3 0.87 Normal Ia past maximum. SNID suggests a redshift of z ~ 0.07.
 04:00     2020adrp classification Gr13 1 900 1.3 0.84 Normal Ia at peak. z ~ 0.06 from SNID.
 04:23 2020znl followup Gr13 1 1800 1.0 1.18 
 05:01 2020aeqv classification Gr13 1 900 1.4 0.80 Another normal Ia around peak. SNID suggests z ~ 0.06.
 05:23 2020acpi classification Gr13 1 900 1.5 0.94Clear SN II. SNID shows good matches with several IIP at ~ +20 to +40 days. Host z = 0.017.
 06:05 2020aerm classification Gr13 1 900 1.2 1.14 Normal Ia near max. SNID suggests z ~ 0.09.
 06:25 2020adnu classification Gr13 1 300 1.3 1.01 Yet another Ia near max. SNID redshift consistent with host z = 0.031.
 06:37 2020aeph classification Gr13 1     900 1.4 1.07 SN II. SNID suggestst z ~ 0.03. Flattish ATLAS light curve suggests IIP.
 07:00 2020acsk classification Gr13 1 900 1.9 0.84 SN II. Host z = 0.029. SNID favours II-pec and matches with 1987A.
 07:24 L745A standard Gr11, 13, 16 1 900 1.2 0.93 
 07:44 2020adnw classification Gr13 1 600 1.3 1.12 SN Ia near max. SNID redshift consistent with host z = 0.036.
 08:00 2020acph classification Gr13 1 600 1.6 1.33Noisy spectrum. SN Ia?
 08:25 2020adlh classification Gr13 1 300 1.2 1.14 Centred the right object this time! SN Ia past max, at z ~ 0.04 from SNID.
