SUPERNOVAE 2013gl IN IC 701

  Further to CBET 3421, P. Lu, W. Zheng, S. B. Cenko, W. Li, and A. V.
Filippenko report the LOSS discovery of an apparent supernova on unfiltered
KAIT images:

 SN       2013 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2013gl   May 9.17    11 31 00.48  +20 28 10.3   16.7    2".6 W, 1".6 N

The variable was designated PSN J11310048+2028103 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2013gl based on the
spectroscopic confirmation reported below.  Additional CCD magnitudes for
2013gl:  Apr. 30.21 UT, [18.7 (KAIT); May 11.977, 16.9 (Gianluca Masi and
Francesca Nocentini, remotely with a 43-cm telescope at Ceccano, Italy;
position end figures 00s.47, 09".8; their image can be viewed at website URL

remotely using a 51-cm RCOS telescope + luminance filter + STL11K camera at
the New Mexico Skies observatory near Mayhill, NM, U.S.A.; interference due
to proximity to galaxy nucleus; position end figures 00s.57, 09".3; image
