SUPERNOVA 2006bl IN MCG +02-40-9
     S. Blondin, M. Modjaz, R. Kirshner, and P. Challis,
Harvard-Smithsonian Center for Astrophysics, report that a spectrum
(range 350-740 nm) of SN 2006bl (cf. CBET 462, IAUC 8698), obtained on
Apr. 23.34 UT by J. Hernandez (University of Michigan) with the F. L.
Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-II
supernova around maximum light.  The spectrum contains P-Cyg profiles
of the Balmer series and helium.  Adopting the NED recession velocity
of 9708 km/s for the host galaxy (taken from "The Updated Zwicky
Catalog", http://tdc-www.harvard.edu/uzc/), the maximum absorption in
the H_alpha line is blueshifted by approximately 9000 km/s.
