S. B. Cenko, A. V. Filippenko, and J. M. Silverman, University of California, Berkeley, report that they obtained a CCD spectrum (range 340-1050 nm) of 2012ck on May 21.45 UT with the Kast double spectrograph on the Shane 3-m telescope at Lick Observatory. The spectrum is dominated by a largely featureless blue continuum, with superimposed narrow emission lines from the underlying host galaxy establishing a redshift of 0.042. These properties are suggestive of a very young type-II supernova. Further observations are encouraged to verify this classification.
