Subject: Supernova in M100

Hi all,
The Central Bureau for Astronomical Telegrams report in Circular No. 8667  
and in Electronic Telegram No. 393 the discovery of a supernova in this well  
known galaxy at about magnitude 15.3 and brightening. 
    It's in Coma, magnitude 9.3, and is a SB spiral (subtype  SBbc)
   Those of you with CCD cameras and moderately powerful  telescopes should 
easily be able to image the supernova.
SUPERNOVAE 2006X was discovered independently by  Shoji Suzuki  
(Ooami-Shirasato, Chiba, Japan, via twelve CCD frames taken on Feb. 4 with a  0.32-m f/9 
telescope + SBIG infrared-cut filter; and by M. Migliardi  (Cortina, Italy)

SN      2006 UT      R.A.   (2000.0)  Decl.    Mag.      Offset
2006X   Feb. 7.10   12 22 53.99  +15 48  33.1  15.3  12" W, 48" S
It is stated  that the supernova does not appear on Palomar Sky Survey 
infrared, red, and  blue  plates.                        
R. Quimby, University of Texas; P. Brown, Pennsylvania State University; and 
C.  Gerardy, Imperial College, report that a spectrogram obtained on Feb. 8.35 
UT  with the 9.2-m Hobby-Eberly Telescope under poor conditions, shows it to 
be an  early type-Ia supernova.
R. Quimby and M. Sellers,  University of Texas, add that SN 2006X appeared at 
mag about 15.3 on unfiltered  CCD images taken on Feb. 7.31 UT with the 
0.45-m ROTSE-IIIb telescope at the  McDonald Observatory; the position for 2006X 
was measured as R.A.  =
12h22m53s.88, Decl. = +15o48'31".9 (equinox 2000.0; uncertainty +/-  0".6).
