We report the following classifications of optical transients from spectroscopic observations with the LRIS spectrograph on the Keck I telescope. Targets were supplied by YSE. All observations were made on 2021 Jan 13 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS21ag | AT2021jw | 04:17:34.23 | -08:15:37.93 | 0.060 | Ic-BL | |
PS21cu | AT2021pj | 09:15:27.20 | +31:48:27.40 | 0.042 | II | | (1)
Notes:
When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy. (1) We measure an H alpha velocity of -9,100 km/s.
