SUPERNOVAE 2006du, 2006dx, 2006dy, 2006dz, 2006ea, 2006eb, 2006ec
Six additional apparent supernovae have been discovered on CCD
images (all unfiltered except for 2006dz): 2006dx by the "Nearby
Supernova Factory" collaboration (cf. CBET 584) on NEAT images
obtained at Palomar; 2006dy by K. Itagaki (communicated by S.
Nakano; cf. IAUC 8700); 2006dz by C. Contreras and G. Folatelli
(Carnegie Supernova Project) on images obtained in six different
optical bands at Las Campanas Observatory; 2006ea and 2006ec by N.
Joubert, D. Madison, D. Winslow, and W. Li (LOSS/KAIT; cf. IAUC
8733); and 2006eb by R. Quimby (cf. IAUC 8622, 8723).

SNe 2006du (cf. IAUC 8733) and 2006dx are both type-II supernovae
(details given on CBET 584). Additional available magnitudes for
2006dy in NGC 5587: 2002 Jan. 19, [19.0 (Itagaki); 2006 June 28,
[19.5 (Itagaki); July 22.22 UT, 18.5 (Li, via KAIT); 26.20, 16.5
(Li, via KAIT). Itagaki adds that nothing is visible at the
position of 2006dy on the Digitized Sky Survey. Li reports the
following position end figures for 2006dy from a KAIT image taken
on July 26.20: 11s.55, 13".8. SN 2006dy is a type-Ia supernova,
some 10 days before maximum light on July 26 (cf. CBET 587).
Further to the tabulated Sloan r' magnitude above, additional
magnitudes for 2006dz in NGC 5185: May 17, [21.7; June 4.10, 19.0;
5.15, 19.0; 7.10, 18.9; 8.09, 18.9; 11.07, 19.0; 12.09, 19.0
(additional details given on CBET 588). Additional KAIT magnitudes
for 2006ea in UGC 12134: 2005 Nov. 20.12, [19.5; 2006 July 10.36,
[18.7; 26.39, 18.8. SN 2006ea is probably a type-Ib event, about 1
week past maximum on July 27 (details on CBET 589). Additional
magnitudes for 2006eb in UGC 771: 2005 Aug. 22-Dec. 3 (co-addition
of images), [19.0; 2006 July 24.41, 17.5. SN 2006eb is a type-Ia
supernova some weeks past maximum (details on CBET 592).
Additional KAIT magnitudes for 2006ec in MCG -04-55-14: July 3.44,
[18.6; Aug. 5.46, 17.0. A KAIT image from July 16.45 also shows a
hint of 2006ec (limiting mag 17.4).
