MASTER OT J163343.30+294131.6 discovery - possible SuperNova in SDSS J163343.29+294130.7 galaxy
MASTER-Tunka auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 16h 33m 43.30s +29d 41m 31.6s on 2015-04-20.71818 UT.
The OT unfiltered magnitude is 18.8m (limit 20.0m).
This MASTER PSN is seen at 3 images. We have 60 images without this PSN from 2010-08-24UT in MASTER-Tunka database, for ex., on 2011-05-10.686 UT with unfiltered magnitude limit.
There is no minor planet at this place.
There is SDSS J163343.29+294130.7 galaxy with g=22.819, r=22.999 in 0.904" from MASTER OT.
The discovery and reference images are available at http://master.sai.msu.ru/static/OT/MASTERJ163343.30+294131.6.jpg
Spectral observations are required.
