SUPERNOVA 2010ax
Filip Novoselnik reports the discovery of an apparent supernova (mag 17)
on three images (limiting magnitude about 20.0) taken on Mar. 15.1 UT with a
0.45-m f/2.8 telescope at Sagra mountain in southern Spain in the course of
the "La Sagra Sky Survey" (LSSS; team members including also Denis Vida,
Ivica Skokic, Robert Gregic, Salvador Sanchez, Jaime Nomen, Reiner Stoss,
Bill Yeung, Juan Rodriguez, and Miguel Hurtado).Stoss measures the position
of the new object as R.A. = 14h41m53s.42 +/- 0s.01, Decl. = +10o45'01".4 +/-
0".1 (equinox 2000.0), which is 6" east and 6" north of the nucleus of the
presumed host galaxy (which may be PGC 1383919).Nothing is present at this
position on a Digitized Sky Survey image from 1989 Mar. 31 (limiting red mag
22), on a Sloan Digital Sky Survey image from 2003 Apr. 25 (limiting
infrared mag 22.3), or on images from the NEAT survey.Stoss adds that
another LSSS image taken on Mar. 23.02 shows 2010ax at mag 18.0.After
a request from Stoss, A. Drake (California Institute of Technology) writes
that Catalina Sky Survey (CSS) images from Mar. 16.12 show 2010ax, noting
that it was not visible in CSS images from 2009 Aug. 1.
