EDITORIAL ANNOUNCEMENT
The editor will be away from August 28 returning on September 10.
However this is a working break during which time I shall still be preparing
the August issue. Please continue to e-mail any contributions to the editor
(who will remain in touch on the internet) or sub-editors by September 5.

However during this period Nick James and Denis Buczynski will undertake the
issue of circulars. For potential discoveries please also advise them of the
details and they will undertake an investigation.

SUPERNOVA 2013ez = GRB 130215A
A. de Ugarte Postigo, Instituto de Astrofisica de Andalucia (IAA) et. al.,
on behalf of a larger collaboration, report that they have been monitoring
the optical counterpart of GRB 130215A discovered with the Swift satellite
on 2013 Feb. 15.064 UT (GCN Circular 14204), citing position R.A. =
2h53m55s, Decl. = +13d22'14" (2000) and unfiltered CCD mag 14.2 on Feb.
15.072. 
Spectroscopy was obtained of the optical counterpart with the 10.4-m Gran
Telescopio Canarias (GTC) at Roque de los Muchachos Observatory in La Palma,
Spain, around Mar. 12.87, at 25.8 days after the onset of the gamma-ray
burst, which is 16.2 days after the burst in the host-galaxy rest frame. The
spectrum has been compared to a series of supernovae templates and a good
match is obtained when compared to a number of type-Ic supernovae, including
broad- lined and normal events such as SN 2002ap and SN 1994I around maximum
light and up to +10 days. A comparison of the spectrum of GRB 130215A with
that of SN 2002ap has been posted by the authors at the following URL:
