[vsnet-id 742] NSV 4082

NSV 4082 was catalogued by Bidelman and MacConnell
(1973AJ.....78..687B) to be a possible Mira star.  The position they
give is only accurate to about 1'.  I have looked up the area on
Stardial images (http://vsnet.astro.uiuc.edu/stardial/), and found GSC
04853-01862 to be the most probable candidate (1.5' SW from the NSV
position).  It is clearly variable on the POSSI and SERCEJ plates (from
the USNOFS Image and Catalogue Archive operated by the United States
Naval Observatory, Flagstaff Station
http://vsnet.nofs.navy.mil/data/fchpix/), taken at different epochs.

The Stardial images show an amplitude of somewhat less than 2
magnitudes (unfiltered CCD), and a period of 304 days (epoch maximum JD
2451538).  

Position (USNO-B1.0 0867-0188840): 08 26 26.80 -03 17 43.7.

Other ID's (found through the VizieR utility of the CDS):
GSC 2.2 S102011116246 
IRAS 08239-0307  
2MASS 126.611699 -03.295481 
ROSAT 1RXS J082610.8-031955 (given by Voges et.al. 1999A&A...349..389V;
seems doubtful however as it is more than 2' distant)
