MASTER OT J131847.92+672030.3 discovery - possible SN in SDSS galaxy J131848.80+672028.6
MASTER-Tunka auto-detection system (
Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 13h 18m 47.92s +67d 20m 30.3s on 2015-03-22.73999 UT.
The OT unfiltered magnitude is 18.4m (the limit is 20.2m).
There are 3 images with OT . We have reference image without OT on 2012-02-27.86169 UT with 19.8 unfiltered magnitude limit in MASTER-Tunka database.
There is SDSS J131848.80+672028.6 galaxy with g_mag=19.56 r_mag=19.11, so this OT is posible SuperNova in it.
The discovery and reference image are available here http://master.sai.msu.ru/static/OT/MASTERJ131847.92672030.3.png
Spectral observations are required.
