SUPERNOVA 2010dt IN PGC 58829
     Filip Novoselnik, on behalf of the La Sagra Sky Survey (LSSS) supernova
search team (which includes also Denis Vida, Ivica Skoki, Robert Gregi,
Salvador Sanchez, Jaime Nomen, Reiner Stoss, Bill Yeung, Juan Rodriguez, and
Miguel Hurtado), reports the discovery of an apparent supernova (mag 18.6) on
two CCD images (limiting magnitude about 20.0) taken on June 1.986 and 1.9995
UT with a 0.45-m telescope.  The new object is located at R.A. = 16h43m14s.68,
Decl. = +32d40'30".4 (equinox 2000.0), which is 21" east and 12" south of the
nucleus of the galaxy PGC 58829.  Nothing is visible at this position on
a Digitized Sky Survey image from 1993 Apr. 28 (limiting red mag 22) or on
a Sloan Digital Sky Survey image from 2003 Mar. 7 (limiting infrared mag
22.3).  J. Brimacombe, Cairns, Australia, reports that he found 2010dt at
mag 17.9 on six co-added 600-s unfiltered images taken remotely on June 5.15
with a 0.51-m telescope (+ STL11K camera) at the New Mexico Skies
Observatory near Mayhill, NM, U.S.A.; his image has been posted at the
