SUMMARY:M31N 2015-01a - A Luminous Red Nova in the Andromeda Galaxy 
DESCRIPTION:M31N 2015-01a - A Luminous Red Nova in the Andromeda Galaxy \nD
 r. Peter Pessev\n\nMASTER-Kislovodsk auto-detection system discovered a  f
 aint transient in the Andromeda galaxy on January 13th 2015. It was  origi
 nally identified as a classical nova and received designation M31N  2015-0
 1a. Further observations showed discrepancies with the spectra and  lightc
 urves typical for the classical novae. The transient was  re-identified as
  a likely stellar merger (aka Luminous Red Nova (LRN)),  similar to V838Mo
 n. In this presentation I will deliver a short overview  of our current un
 derstanding of this class of objects and a summary of  the current state o
 f the ongoing observing campaign of the M31 LRN.  Recent results will be d
 iscussed with a particular emphasis on the  contributions made possible by
  GTC and other observing facilities at  Observatorio Roque de los Muchacho
 s. At the final part of the  presentation I will touch on follow up observ
 ations once M31 is  available for observations again.
