MASTER OT J034838.11-274913.4 detection - PKS 0346-27 flare

MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",Advances in Astronomy, 2010, 30L )
detected OT source at (RA, Dec) = 03h 48m 38.11s -27d 49m 13.4s on 2018-03-11.05672 UT.
The OT unfiltered magnitude is 15.8m (mlim=18.7m).
The OT is seen in 48 images. We have reference image on 2016-09-27.32462 UT with m_OT<~19.2 and 19.2 unfiltered magnitude limit.
There is PKS 0346-27 http://simbad.u-strasbg.fr/simbad/sim-id?Ident=PKS%200346-27

MASTER OT J043510.14-464138.9 detection - dwarf nova outburst, ampl>3.6m

MASTER-OAFA auto-detection system discovered OT source at (RA, Dec) = 04h 35m 10.14s -46d 41m 38.9s on 2018-03-11.12385 UT.
The OT unfiltered magnitude is 17.0m (mlim=18.5m). The OT is seen in 4 images. There is no minor planet at this place.
We have reference image without OT on 2016-08-05.37566 UT with 20.6 unfiltered magnitude limit, it means more then 3.6mag amplitude of current outburst.
There is GALEX source and USNO-B1 star.
Spectral observations are required.
