MASTER OT J050605.96-471343.0 discovery - PSN in 17.5"W,1.1"N of PGC130509
MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 05h 06m 05.96s -47d 13m 43.0s on 2020-01-23.17579 UT.
OT unfiltered magnitude is 17.5m (mlim=20.1).
The OT is seen in 2 images. There is no minor planet at this place.
We have reference image on 2019-12-20.20257 UT with unfiltered 20.7m.
Spectral observations are required.
This PSN is in S0(a) PGC130509 galaxy.

MASTER OT J085243.03-585755.8 discovery - preliminary dwarf nova outburst with ampl>3.6, no known VIZIER data
MASTER-OAFA auto-detection system discovered OT source at (RA, Dec) = 08h 52m 43.03s -58d 57m 55.8s on 2020-01-23.25532 UT.
The OT unfiltered magnitude is 18.4m (mlim=18.9).
The OT is seen in 2 images. There is no minor planet at this place.
We have reference images on 2020-01-22 05:26:27UT with mlim=18.7, on 2018-04-13.07763 UT with mlim=19.8m.
There is no any data in VIZIER database, it means 22m POSS limit in history and more then 3.6m of current outburst amplitude.
Spectral observations are required.
