MASTER OT J172624.20+335044.4 discovery - possible superluminous SN in SDSS far galaxy
MASTER-Kislovodsk auto-detection system (
Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 17h 26m 24.20s +33d 50m 44.4s on 2015-04-01.97351 UT.
The OT unfiltered magnitude is 17.6m (limit 18.9m) and is seen in 5 images. There are images of OT on 2015-04-04.953UT with m_OT=18.1.
We have reference image without OT on 2014-04-11.987UT with 19.6 unfiltered magnitude limit.
There is SDSS galaxy with g_mag=21.86, r_mag=21.38 in 0.128 arcsec of our PSN.
Spectral observations are required.
