We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by ZTF. All observations were made on 2020 May 23 UT.
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF20aaurjbj | AT2020hgw | 14:18:19.13 | +38:55:46.28 | 0.043 | II | | (1)
ZTF20aazpphd | AT2020jww | 16:10:51.59 | +27:09:42.10 | 0.046 | 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 an H-alpha absorption velocity of -3900 km/s. (2) We detect broad H-alpha emission and a slight absorption feature, which if H alpha, has a velocity of -15,300 km/s.
We thank the Lick Observatory staff for their dedication and hard work to make these observations possible.
