NSV 1436 OUTBURST
Eddy Muyllaert, Belgium has reported a bright outburst of the 
cataclysmic variable NSV 1436 recorded at magnitude 13.5 on 2011 March 
28.957UT using an image obtained with the Bradford Robotic Telescope. It 
is located at:
RA 04h02m39.02s DEC +42 50' 46.0" (2000).

AAVSO Alert 434 by Matthew Templeton relays that this is the first 
recorded bright outburst of this star observed since 1948, and follow-up 
observations are strongly encouraged.  Little is known about the nature 
of NSV 1436, and observations may help shed light on whether the star is 
an infrequently outbursting normal dwarf nova, a WZ Sge star, or 
recurrent nova.

The outburst has been confirmed by M. Linnolt, USA at visual magnitude 
of 12.8 on March 30.2708UT.  This star last exhibited a bright outburst 
in late November 1948 (Brown et al., 2010, JAAVSO 38, 176), and is a 
known X-ray source (Bedient 2004, priv. comm.). A smaller outburst 
occurred on 2011 March 9-10, when it briefly reached magnitude ~14.5 
(Linnolt: 14.5 on JD 2455629.7618; M.
Simsonsen, Michigan, United States: V=14.55 on JD 2455630.6615; Linnolt: 
14.55 on JD 2455630.7354).  The classification of this object is 
unclear, in large part because it has been poorly observed in the past.
The object is typically fainter than V=16, and has been recorded as 
faint as magnitude 19.  Photometry during the current outburst may 
provide insight into the nature of this object.

Please report all observations of this star to Gary Poyner for 
publication in TA and to the AAVSO using the name "NSV 1436".

N. Morrell, Las Campanas Observatory and others report that a spectrum 
on Mar. 5.4UT is of a young, normal type-Ib supernova, about a week 
before maximum.
