We report the classification of SN 2022ibv with the GMOS spectrograph on the Gemini-North Telescope with GMOS on UT 2022 Apr 23. The target was supplied by ATLAS. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ATLAS22mnd | AT2022ibv | 10:49:04.17 | -29:22:29.69 | 0.0144 | II | young | (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) The spectrum has a nearly featureless blue continuum. We detect a relatively narrow H-alpha emission feature with FWHM = 1,400 km/s
