We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. The targets were supplied by ASASSN and the Young Supernova Experiment. All observations were made on 2022 July 28 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Notes
ASASSN-22jo | AT2022pru | 11:59:07.83 | +52:41:57.66 |0.003606| II | (1)
PS22gjh | AT2022prv | 15:40:07.75 | +20:40:31.78 |0.015101| II | (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) We measure a H-alpha absorption velocity of -11,300 km/s.
(2) At the distance of its host galaxy, IC 1132, AT2022prv is currently M = -15.2 mag. While possible this is an LBV outburst, the luminosity is more consistent with a SN II. We measure a H-alpha FWHM of 3200 km/s.
