Discovery Date: 2007 November 14.23 UT (JD 2454418.73)

Discovery Magnitude: approximately 7.0 (visual estimate)

Position: R.A. = 8h 16.2m Decl. = -34o 15' (J2000) from Pereira.

RA = 08h 16m 18.01s Decl. = -34o 15' 24.1" (J2000) by J.E. McGaha, Tucson, Arizona, measured with CCD imaging on November 14.243 - 14.256 UT.

RA = 08h 16m 17.99s Decl. = -34o 15' 25.0" (J2000) by J. Young and H. Rhoades, Table Mountain Observatory, near Wrightwood, California, measured with CCD imaging on November 14.47 - 14.48 UT.

Pereira reports nothing at this position on November 6.23, 7.22, 8.23, 10.23, and 11.22 UT down to a limiting visual magnitude of approximately 8.

McGaha reports a CR magnitude of 6.5 on November 14.411 (JD 2454418.91), measured relative to USNO-A2.0.

Young reports a visual magnitude estimate of 6.4 on November 14.47 (JD 2454418.97)

Notes: J. Young (Table Mountain Obs.) also reports that a red image of the field from the Digitized Sky Survey contains a point source at an approximate magnitude of 20.

Spectra have not yet been published so the nova type is not yet known.
