J. Christensen, Lunar and Planetary Laboratory, University of Arizona, reports on CBET 746 his discovery of an apparent high-amplitude variable star on unfiltered CCD images obtained in the course of the Catalina Sky Survey. The position of the variable given as: RA 10h 21m 46.42s DEC +23 49' 26.2" (2000). Approximate V magnitudes Oct. 28.503-28.523 UT, 13.9; Nov. 17.533-17.537, 14.4. There is an object at V around 21 at this position in an archival CSS image, and there is a star catalogued in the Sloan Digital Sky Survey DR5 database with the following magnitudes: u = 20.83, g = 20.74, r = 20.63, i = 20.84, z = 20.45. K. Ayani, Bisei Astronomical Observatory et. al., report that they obtained spectra with the BAO 1.01-m telescope at Ibara, Okayama, Japan, on Nov.21.8 UT which showed characteristics of a dwarf nova in outburst. SUPERNOVAE 2006nf-2006np According to IAUC 8776, eleven new type-Ia supernovae, as designated above, in the magnitude range g = 21.0-23.0) have been found during the Sloan Digital Sky Survey II. SUPERNOVA 2006nq This object has been reported by the 'Nearby Supernova Factory' as a type II of magnitude R=19.7) recorded on Nov 13.2UT.
