VARIABLE IN HERCULES
IAUC 8601 reports that T. Puckett and V. Reddy have discovered a mag 16.2
variable object in Hercules on an unfiltered CCD frame taken with the
0.60-m automated supernova patrol telescope on Sept. 6.08 UT. The position
of the object is R.A. = 17h48m05s.81, Dec. = +34o04'01".2 (equinox
2000.0), which is near UGC 10990.

The object is also visible at mag 16.6 on Puckett's images from Sept. 7.09
and on Palomar Sky Survey plates taken on 1992 May 5 (blue mag 19.7) and
1993 Aug. 12 (red mag 17.7).  Nothing is visible at this location on
images taken by Puckett on 2000 Apr. 18, 26, May 12, June 9, 30, 2002 Mar.
8, Apr. 6, 16, 2003 Apr. 6, 14, and 2005 Feb. 26 (limiting mag about
20.0); however, the variable was visible at the following magnitudes on
other images taken by Puckett:  2002 Feb. 25, 18.1; 26, 18.3; Mar. 24,
18.7; Apr. 1, 17.8; 2004 July 10, 18.2; 2005 Apr. 5, 18.0; 13, 17.8; 17,
17.4; 20, 17.1; 25, 17.5; May 8, 17.0; 14, 16.8; 19, 17.1; 26, 17.5; 29,
18.0; June 6, 17.5; 23, 17.7.  The variable object's location is very near
that of the radio source IVS 1746+340 (cf. Beasley et al. 2002, Ap.J.
Suppl. 141, 31).
