We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by ASAS-SN and ATLAS. All observations were made on 2017 Oct 28 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name        | IAU Name  | RA (J2000)  | Dec (J2000)  | z     | Type | Phase | Notes
ATLAS17mup | AT2017hqb | 23:30:56.28 | +23:11:12.62 | 0.062 | Ia | +2 d | (1) ATLAS17mum | AT2017hpl | 02:10:28.23 | -16:58:52.01 | 0.07 | Ia | +1 d | ATLAS17mlu | AT2017hmx | 03:55:33.24 | +33:16:00.86 | 0.073 | Ia | +7 d | ATLAS17msi | AT2017hoq | 05:19:20.29 | -17:36:41.72 | 0.02 | Ia | -2 d | (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 Si II 6355 velocity of -10,800 km/s. (2) We find weak CII 6580 line in the spectrum.
