SUPERNOVA 2009hd IN M66
     Further to CBET 1867, H. Yamaoka, Kyushu University, reports the
following pre- and post-discovery unfiltered CCD magnitudes by K. Itagaki
(Teppo-cho, Yamagata, Japan) obtained with 50-cm and 60-cm reflectors:  June
23.480 UT, 17.2; 26.498, 16.3; July 5.486, 16.1.
     M. M. Kasliwal, California Institute of Technology; and D. K. Sahu and
G. C. Anupama, Indian Institute of Astrophysics, Bangalore, report that a
low-resolution spectrogram (range 350-900 nm), taken in poor weather
conditions on July 8.703 UT with the Hanle Faint Object Spectrograph Camera
on the 2-m Himalayan Chandra Telescope, indicates that 2009hd (cf. CBET 1867)
is a reddened type-II supernova.  The only prominent feature is a two-
component H-alpha emission (broad and narrow) that is consistent with the
redshift of M66; the gaussian FWHM of this feature corresponds to a velocity
of approximately 5000 km/s.
