SUPERNOVA 2009gj in NGC 134
     R. J. Foley, Harvard-Smithsonian Center for Astrophysics, reports that a
CCD spectrum (range 305-1000 nm), obtained on June 24 UT with the 6.5-m
Magellan Clay telescope (+ MagE), shows that 2009gj (cf. CBET 1856) is a
type-IIb supernova.  The spectrum is similar to that of SN 1993J at about
three weeks after explosion.  Adopting a redshift of 1750 km/s (measured from
Na D absorption), the H_alpha P-Cyg absorption minimum is blueshifted by
13000 km/s.
     Further to CBET 1856, P. Marples writes that the limiting red magnitude
of Bocks' unfiltered 30-s image from 2007 Nov. 19 is 17.2, as measured by
C. Drescher.
