This report includes the spectral observations of two unkonwn objects with blue continuum.

ePESSTO+, the advanced Public ESO Spectroscopic Survey for Transient Objects (Smartt et al. 2015 2015A&A...579A..40S), reports the following supernova classifications.

Targets were supplied by the ATLAS survey (Tonry et al. 2018 2018PASP..130f4505T).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2020 March 21, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution).

The classification spectra and additional details can be obtained from (via WISeREP) and the IAU Transient Name Server.

The classified objects are listed in the Related Objects table below.
