Two new supernovae have been reported from unfiltered CCD images: 2006am in NGC 5630 by E. Lee and W. Li (LOSS/KAIT; cf. IAUC 8669), and 2006an by R. Quimby and F. Castro, University of Texas (0.45-m ROTSE-IIIb telescope; cf. IAUC 8622). SN 2006 UT R.A. (2000.0) Decl. Mag. Offset 2006am Feb. 22.53 14 27 37.24 +41 15 35.4 18.5 7".5 E, 6".8 N 2006an Feb. 21.27 12 14 38.68 +12 13 46.9 17.9 1" W, 1" S Additional KAIT magnitudes for 2006am: 2005 July 4.21 UT, [19.5; Feb. 23.55, 18.5; 24.54, 18.5. SN 2005dp also appeared in NGC 5630. A co-addition of images taken between 2004 Dec. 15 and 2005 June 8 shows nothing at the location of 2006an, with limiting mag about 19.0; 2006an was also detected on 2006 Feb. 26.27 at mag about 17.7. The positional uncertainty for 2006an above is estimated as ± 0".6; the specified offset is with respect to a galaxy that is not significantly detected in the ROTSE-IIIb data, but it appears at mag r = 21.9 in SDSS data with position end figures 38s.73, 47".7. SN 2006an is a type-Ia supernova (cf. CBET 413).
