  MASTER OT J095359.98-333736.2 discovery - PSN in 3.3"E,0.7"N of PGC673735

MASTER-SAAO auto-detection system discovered OT source at
(RA, Dec) = 09h 53m 59.98s -33d 37m 36.2s on 2020-02-11.78015 UT.

The OT unfiltered magnitude is 19.0m (mlim=19.7).

The OT is seen in both 2 inspect images. There is no minor planet at this place.

We have reference image on 2015-01-23.98993 UT with unfiltered mlim= 19.9m.

Spectral observations are required.

The discovery and reference images are available at:
