EDITOR'S ABSENCE
The editor will be away from Thursday May 4 (AM) and will not return 
until Sunday May 7 (PM). During that time I will be giving a talk to 
York Astronomical Society on Friday evening and would be delighted to 
meet anyone planning to attend.

During my absence, please e-mail or ring Nick James or Denis Buczynski 
regarding any URGENT matters eg potential discoveries. Full contact 
details appear on the first page of each issue of 'The Astronomer'.

SUPERNOVA 2006bk IN MCG +6-33-20
Further to the note on E-Circular 2226, S. Blondin, et.al., 
Harvard-Smithsonian Center for Astrophysics, report that a spectrum 
(range 350-740 nm) of SN 2006bk obtained on Apr. 21.31 UT by W. Peters 
with the F. L. Whipple Observatory 1.5-m telescope
(+ FAST), shows it to be a type-Ia supernova, roughly three weeks past 
maximum light.  SN 2006bk was previously classified as a type-Ic 
supernova around maximum light on the basis of a "W-shaped" feature 
around 500 nm.  This feature is due to unresolved blends of Fe II lines, 
and is common to both type-Ia and type-Ic post-maximum spectra -- hence 
the possible confusion.
