We report the classifications of AT2022vpm and AT2022vpu from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2022 Sept 24 UT. The targets were supplied by XOSS and the Young Supernova Experiment (YSE), respectively. The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PSP22ae | AT2022vpm | 17:22:32.885 | +26:46:04.38 | 0.0217 | II | | (1)
PS22jhv | AT2022vpu | 01:19:49.553 | -18:15:02.42 | 0.0493 | SN | | (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) The spectrum shows a blue continuum with a broad bump visible consistent with H-alpha at this redshift.
(2) The spectrum shows a blue, featureless continuum.
