We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. The targets were supplied by the Young Supernova Experiment and ATLAS. All observations were made on 2022 Jan 26 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ATLAS22cko | 2022aev | 07:38:49.307 | +19:26:06.47 | 0 | CV | peak | (1)
PS22tw | 2022ahc | 09:11:50.355 | +29:06:06.72 | 0.09| Ia | +2 | (2)
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) Blue continuum, H-alpha at z=0 and a point source in Legacy Survey images are consistent with a CV.
(2) We measure a Si II 6355 velocity of -11,500 km/s.
