We report the following classifications from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2022 June 02 UT. The targets were supplied by ZTF with AT2022gnr and AT2022kie reported by ALeRCE and SGLF, respectively. The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF22aaegxpa| AT2022gnr | 21:44:40.036 | +02:13:41.38 | 0.0401 | II | +100d | (1)
ZTF22aakelti| AT2022kgh | 13:50:56.279 | +28:47:45.46 | 0.0570 | II | +2d | (2)
ZTF22aaknhja| AT2022kie | 16:26:43.334 | +25:38:42.66 | 0.0667 | Ia | -2d | (3)
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 FWHM of 8300 km/s.
(2) We measure a H-alpha FWHM of 6400 km/s.
(3) We measure a Si II 6355 Velocity of -10,000 km/s.
