SUPERNOVAE 2006es, 2006et, 2006eu

Three apparent supernovae have been discovered on unfiltered
CCD images:  2006es and 2006eu by J. Schwehr, N. Lee, and W. Li
(LOSS/KAIT; cf. IAUC 8744); and 2006et by K. Itagaki (Teppo-cho,
Yamagata, Japan; via S. Nakano, Sumoto, Japan).  Additional
magnitudes for 2006es in UGC 2828:  Feb. 14.20 UT, [19.5; Aug.
14.53, 17.0 (poor seeing).  SN 2006es is a type-Ia supernova, now
about 3-4 weeks past maximum brightness (cf. CBET 613).  Additional
magnitudes for 2006et in NGC 232:  Aug. 24.69, [18.5; 30.68, 17.0.
Nothing was visible at the location of 2006et on Itagaki's survey
frames taken prior to Aug. 24 (limiting mag 19) or on the Digitized
Sky Survey.  Additional KAIT magnitudes for 2006eu in MCG +08-36-16:
Aug. 16.23, [19.5; 25.22, 19.1: (hint, at limit); Sept. 4.26, 17.2.
