Abstract:
Here we report the classification of 5 optical transients with 2 SN Ia: SN 2020tjo, SN 2020vem; 1 SN IIP: SN 2020tet; 1 SN IIn: SN 2020tyk; and 1 SLSN: SN 2020xgd.

The Recommender Engine For Intelligent Transient Tracking (REFITT) collaboration reports the following 5 classifications from SOAR AEON observations with the Goodman Spectrograph (Clemens et al. 2004). Targets were selected from the Zwicky Transient Facility (ZTF; Bellm et al. 2019) processed through the Antares data broker (Narayan et al. 2018). Classifications, and the associated redshifts, were made using SNID (Blondin and Tonry 2007) and DASH (Muthukrishna et al. 2019), unless otherwise noted.
