We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by PSST and ASAS-SN. All observations were obtained on 2018 Jan 14 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name        | IAU Name  | RA (J2000)  | Dec (J2000)  | z     | Type | Phase | Notes
PS17fvd | AT2017jmj | 10:43:50.40 | +06:45:54.50 | 0.028 | Ic | | (1) PS18bq | AT2018bi | 02:19:53.28 | +29:02:02.70 | 0.017 | Ia | +1 d | (2) ASASSN-18af | AT2018bs | 03:23:20.74 | -22:06:59.47 | 0.07 | Ia | -2 d | ASASSN-18al | AT2018ep | 11:22:40.65 | +12:01:31.37 | 0.040 | Ia | +5 d | (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) Also some reasonable matches to SNe Ia. (2) Classification is consistent with that of ATel #11168. We measure an Si II 6355 velocity of -10,300 km/s. (3) We measure an Si II 6355 velocity of -9,800 km/s.
