SUPERNOVA 2013ek IN NGC 6984 = PSN J20575390-5152245
     S. Valenti, Las Cumbres Observatory Global Telescope (LCOGT) and
University of California at Santa Barbara (UCSB); D. Sand, Texas Tech
University; D. A. Howell and M. L. Graham, LCOGT/UCSB; and J. T. Parrent,
LCOGT and Dartmouth College, report that a spectrogram (range 320-1000 nm) of
PSN J20575390-5152245 = SN 2013ek (cf. CBET 3607), obtained robotically with
the FLOYDS spectrograph on the "Faulkes Telescope South" at Siding Spring on
July 25.42 UT, shows typical features of type-Ib/c supernovae.  Fits to a
library of spectra using the Superfit, Gelato, and SNID software indicate that
2013ek is likely a type-Ib supernova within a week of maximum light.  Given
the classification of the very nearby SN 2012im as a type-Ic supernova by
PESSTO (see URL http://www.astronomerstelegram.org/?read=4300) and the
spectrum of SN 2013ek, it is considered likely that these are two different
objects.
