We report the following classification of AT2019mhm from spectroscopic observations with the FLOYDS spectrograph on the 2-m Faulkes-South telescope at Siding Spring Observatory, New South Wales, Australia. The target was supplied by BOSS. Observations were made on 2019 August 4 UT. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name      | RA (J2000)   | Dec (J2000)  | z      | Type  | Phase    | Notes
 
AT2019mhm | 19:11:24.060 | -57:03:18.0  | 0.0106 | II    | 0        | (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 P-Cygni H-alpha emission with a FWHM in the redshifted emission of 11,400 km/s. We infer that this source is a SN II at or around optical maximum.
