12 transients have been discovered as part of the Kepler K2 Campaign 14 search using the Pan-STARRS telescope augmenting the Pan-STARRS Search for Transients (PSST) http://star.pst.qub.ac.uk/ps1threepi/. (See Chambers et al. arXiv:1612.05560, Huber et al. ATel #7153.) Four of the transients are located near K2 Campaign 14 galaxies.
