AAVSO Special Notice #187
Possible Nova in Oph
January 17, 2010
CBET 2128 indicates that Hideo Nishimura has discovered a new outbursting object in Ophiuchus [V2673 Oph]. This object has magnitude 8.4 on Jan 15.857UT, and is located at RA 17:39:40.94 DEC -21:39:47.9 J2000 No spectra have been reported, but K. Kadota has inspected the 1997 DSS red plate and finds no object at this position, with a limiting magnitude of 20. We have a preliminary Tycho sequence, but will extend it fainter with ASAS soon. The object has not yet been assigned a VSX identifier. Note that there is a 10.3mag irregular variable a few arcmin west of this position, so do not use it as a comparison star. An image from K. Itagaki can be found at http://www.k-itagaki.jp/images/pn-sgr.jpg This special notice prepared by A.
