Two active supernovae have been discovered in the same probable host galaxy, 2MFGC 12659, as part of the Pan-STARRS Survey for Transients (PSST). The transients were not present in z-band (limiting magnitude 20.4) and y-band (limiting magnitude 18.7) exposures taken on 20180209, 27 days before the discovery date.
Information on all objects discovered by the Pan-STARRS Survey for Transients is available at http://star.pst.qub.ac.uk/ps1threepi/ (see Huber et al. ATel #7153). We encourage spectroscopic classification of these relatively bright SN candidates.

NED reports that the probable host galaxy is 2MFGC 12659, with spectroscopic z=0.047961, assumed distance 206Mpc, M-m = 36.56, A_i = 0.028.
(1) 3.0 arcsec from the host. At the host redshift the absolute magnitude is M_i = -18.17
(2) 7.2 arcsec from the host. At the host redshift the absolute magnitude is M_i = -17.46
