SUPERNOVA 2004el IN MCG +09-25-004
     M. Modjaz, P. Challis and R. Kirshner, Harvard-Smithsonian Center for
Astrophysics; and T. Matheson, National Optical Astronomy Observatory,
report that a spectrum (range 350-740 nm) of SN 2004el (cf. CBET 81),
obtained by P. Berlind on Sept. 17.12 UT with the F. L. Whipple
Observatory 1.5-m telescope (+ FAST), reveals it to be a supernova of type
II.  The spectrum consists of a blue continuum with P-Cyg lines of H_alpha
and H_beta.  Adopting the Lyon-Meudon Extragalactic Database recession
velocity of 7885 km/s for the host galaxy, the expansion velocity derived
from the minimum of the H_beta line is 9900 km/s.

      formal IAU Circulars.  Citations should normally be made to IAUCs
