NSV 1436 Observation data
Epoch J2000 Equinox J2000Constellation Perseus Right ascension 04h 02m 39.02s Declination +42° 50′ 46.0″ Apparent magnitude (V) 11(outburst)-19(quiet) Characteristics Variable type Cataclysmic variable Astrometry Details Other designations Ross 4, 1RXS J040239.4+425037.Database references SIMBAD data Data sources: NSV 1436, listed in the New Catalogue of Suspected Variable Stars (NSV), is a cataclysmic variable star in the constellation Perseus. It is believed to be similar to a dwarf nova like the star U Geminorum, but little is known.[1] The last outburst observed was in late November 1948.[1] A small outburst occurred on March 09-10, 2011 when it briefly reached about visual magnitude 14.5.[1] A brighter outburst phase began and was observed on March 28, 2011 at visual magnitude 13.49 and confirmed at visual magnitude 12.8 on March 30, 2011.[1]. The object is typically fainter than visual magnitude 16.[1] Observations were requested by the American Association of Variable Star Observers (AAVSO) during the 2011 outburst phase to help classify the object[1], and to see if it is an infrequently outbursting normal dwarf nova like WZ Sagittae or a recurrent nova.[1] The object is a known X-ray source.[1]
Location
NSV 1436 is one of three stars close together in an apparent line, being the third or farthest star away (northward) from the brightest of the three stars. The second star is very close to the brightest or first star.
