Supernovae 2006nr-2006oq
Abstract
Two apparent supernovae have been reported from unfiltered CCD images: 2006nr by T. Puckett and A. Pelloni (0.60-m reflector at Ellijay, GA; cf. IAUC 8567), and 2006oq by E. J. Christensen (Catalina Sky Survey). SN 2006 UT R.A. (2000.0) Decl. Mag. Offset 2006nr Oct. 26.24 5 56 23.51 +85 54 38.8 15.8 41" E, 14" S 2006ob Nov. 18.29 1 51 48.11 + 0 15 48.3 17.6 5".5 W, 1".6 S 2006oq Nov. 17.49 11 44 00.07 +19 58 38.3 15.8 31" W, 17" N Additional magnitudes for 2006nr in UGC 3336: Sept. 15, [19.5 (Puckett); Nov. 12.16, 16.2 (D. Lane, Stillwater Lake, NS, 0.28-m reflector). SN 2006nr is a type-Ia supernova approximately 3 weeks past maximum on Nov. 18 (details on CBET 744). Nothing was visible at the position of 2006oq on 24 CSS images obtained between Mar. 2005 and Apr. 2006 (limiting mag V about 21.5); type-Ia SN 2006oq was about 2 weeks past maximum on Nov. 21 (details on CBET 748). On CBETs 743 and 745, J. Frieman and the Sloan Digital Sky Survey II collaboration report 24 additional supernovae (designated 2006ns-2006op, all in the magnitude range g = 19.8-22.3, and most being type-Ia events) discovered during Oct. 17-Nov. 17. The data in the table above for 2006ob are from M. Baek and W. Li (LOSS, unfiltered KAIT images); additional magnitudes for 2006ob: Oct. 29.30, [18.9 (LOSS); 7.31, [18.5 (LOSS); 13, 19.9 (SDSS II; g band); 19.31, 17.6 (LOSS). SN 2006ob was then an early type-Ia supernova. The non-type-Ia supernovae in this SDSS group are: 2006ns, II; 2006nx, Ib/c hypernova; 2006ny, IIp.
