We report on SALT spectroscopy of MASTER OT J233317.85-674248.4 (AT2020ntu , Minkina et al. ATel #13841)
discovered inside the Fermi GRB200629A BALROG localization (GCN #28039, GCN #28040) inspected by MASTER (GCN #28041, cover map)
on 2020-06-29.976 ,
under the SALT Large Science Programme on transients (2018-2-LSP-001).
A spectrum covering 4060-7000A was obtained on 2020-07-01.0433 of the transient revealing it to be a SN Ia 6 days old in an uncatalogued low luminosity galaxy, located 2.6" from the centre. The host galaxy has z = 0.038.
There is a USNO-B1 object in the VIZIER database with B2=20.66,R2=20.44
Next days follow-up spectra are encouraged.
