We report the following classifications of optical transients from spectroscopic observations with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope. Targets were supplied by Gaia. All observations were made on 2018 Feb 8 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name      | IAU Name | RA (J2000)  | Dec (J2000)  |   z   | Type | Phase |  Notes
Gaia18aih | AT2018og | 12:49:24.06 | -46:55:39.25 | 0.04 | II | | Gaia18ahu | AT2018nw | 13:26:11.76 | -44:26:30.26 | 0.035 | 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) We measure an H alpha velocity of -10,000 km/s.
