SUPERNOVAE 2006jc, 2006jd, 2006je

Three apparent supernovae have been found on unfiltered CCD
images:  2006jc independently by K. Itagaki (Teppo-cho, Yamagata,
Japan; 0.60-m f/5.7 reflector; communicated by S. Nakano, Sumoto,
Japan; tabulated data below from Itagaki; additional details on
CBET 666) and by T. Puckett and R. Gorelli (0.35-m reflector at
Ellijay, GA; cf. IAUC 8758); and 2006jd and 2006je by R. R. Prasad
and W. Li (LOSS/KAIT; cf. IAUC 8758).

Additional magnitudes for 2006jc in UGC 4904:  2005 Dec. 11 UT,
[19.8 (Puckett); 2006 Sept. 21.793, [19.5 (Itagaki); 22, [19.0
(Itagaki); Oct. 10.33, 13.8 (Puckett and Gorelli); 10.725, 13.9
(Itagaki); 11.34, 13.7 (D. Lane, Stillwater Lake, NS, 0.28-m
reflector, via Puckett); 12.191, 13.9 (G. Masi and S. Foglia,
Ceccano, Italy).  Puckett provides position end figures 20s.85,
33".0 for 2006jc.  Itagaki adds that nothing is visible at this
location on the Digitized Sky Survey (DSS).  Masi provides the
following position end figures for 2006jc:  20s.79, 33".1.  SN
2006jc appears to be a peculiar type-Ib/c supernova (details on
CBETs 672, 674, and 677).  Additional magnitudes for 2006jd in UGC
4179:  Apr. 21.17, [19.0; Oct. 15.54, 17.1.  Additional magnitudes
for 2006je in IC 1735:  Sept. 29.36, [19.0; Oct. 17.47, 18.2.  SN
2006je is a peculiar type-Ia supernova (details on CBET 678).
