SUPERNOVA 2010gw IN IC 4992
     Peter Marples, Loganholme, Queensland, Australia, reports the discovery
of an apparent supernova (red mag 16.6) on a 35-s unfiltered CCD image taken
on Aug. 10.61 UT with a 35-cm Celestron C14 reflector (+ SBIG ST10 camera) by
Stuart Parker (Oxford, Canterbury, New Zealand) as a member of the Backyard
Observatory Supernova Search team.  The new object is located at R.A. =
20h23m25s.31, Decl. = -71d34'04".9 (equinox 2000.0), which is 12" west and
11" south of the nucleus of IC 4992 (position and magnitude measured by
Colin Drescher and Greg Bock from the Queensland Astrofest, Camp Duckadang,
Linville, Queensland, Australia, using Astrometrica with the USNO-B1.0
catalogue).  A confirming image taken on Aug. 12.371 by Bock using a Meade
35-cm f/7 reflector (+ ST10 CCD camera; limiting red mag 17.7) shows the
new object clearly, with nothing visible at the position of 2010gw on a
Digitized Sky Survey image (limiting red mag > 19).
