Аннотация: MASTER OT J005559.13+594802.1 detection - possible FUor or Novalike (NL|NC)
MASTER-Kislovodsk auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 00h 55m 59.13s +59d 48m 02.1s on 2015-05-19.92218 UT. The OT unfiltered magnitude is 16.6m (the limit is 18.4m).
This OT is seen in 5 images on 2015-05-19.922:19.232, and on 2014-08-24.728, 2014-03-31.804, 2013-06-18 2013-09-29.525, 2013-06-18.754, 2013-04-03.592 with the same m_OT.
There is no object at the position on the POSS I and POSS II images, but there is red source (ALLWISE, etc) with W2=15.25.
Thus we can suggest a possible FUor (but there is no visible surrounding nebula) or Novalike type of object (NL|NC by GCVS)
Spectral observations are required.
