Confirmation images taken on Nov. 2.572 with a 0.50-m f/6 reflector show the variable's magnitude to be about 15.8, and the position is: RA 23h 11m 10.90s DEC +1 30' 03.1"(2000). It was also detected on Nov. 4.414 at the same brightness, but it was fainter than mag 17.3 on his survey image taken on Oct. 2. Following a request from the Central Bureau K. Kinugasa, Gunma Astronomical Observatory (GAO) et. al., took low-resolution spectra of the variable on Nov. 7.4 with the GAO 1.5-m reflector and on Nov. 7.6 with the BAO 1.01-m reflector, showing a smooth blue continuum with a broad but shallow H-beta absorption being the most prominent feature. The H-alpha absorption is less impressive. Both of the hydrogen features seem to be filled by the emission core. These characteristics suggest that it is a dwarf nova in outburst.

The object was first detected with r-band magnitude 20.8 on Oct. 31 UT and reached maximum light at comparable magnitude around Nov. 2. SN 2007qd is located at RA 2h 09m 33.56a DEC -1 00'02.2"(2000) Guy M Hurst
