We report the following classification of an optical transient from spectroscopic observations with the Kast double spectrograph on the Shane 3-m telescope at Mt. Hamilton, California. The target was supplied by ZTF. Observations were made on 2019 June 14 UT. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Notes
ZTF19aaydpiq | AT2019hhc | 11:21:04.024 | +31:14:57.99 | 0.0238 | II | (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 is dominated by blue continuum emission. We detect narrow (<500 km/s) Halpha emission superimposed on a weak, broader Halpha profile, although the former is likely due to a coincident H II region.
