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.

Host galaxy and redshift information below supplied by NED, unless otherwise stated.

(1) Originally discovered on 20170528 by the PMO-Tsinghua Supernova Survey, PTSS17syx. 10.6" from C14 galaxy SDSS J102513.56+093759.6 (z=0.048863) (EPICID=248756699). Confirmed to be a SNIa in ATel #10513. (2) Outside the C14 galaxy footprint. 5.3' from nearest C14 galaxy. Originally discovered by ATLAS on 20170519. 2.98" from 2MASX J10520439+1135386 (z=0.042902). (3) Outside the C14 galaxy footprint. 6.5' from nearest C14 galaxy. 3.7" from SDSS J110006.36+112902.9. (4) Marginal K2 candidate. Located 0.78" from C14 galaxy SDSS J110529.52+020523.8 (EPICID=248527382). Spectroscopically classified as an AGN (z=0.250) in ATel #10517. (5) Marginal K2 candidate. Located 0.35" from C14 galaxy 2MASX J10315750+0357042 (EPICID=201603032). Spectroscopically classified as a galaxy (z=0.073) in ATel #10517. (6) Outside the C14 galaxy footprint. 4.0' from nearest C14 galaxy. 1.3" from SDSS J105625.45+071059.2. (7) Outside the C14 galaxy footprint. 2.9' from nearest C14 galaxy. 1.9" from SDSS J104347.02+131146.8. Rising. (8) Outside the C14 galaxy footprint. 14.8' from nearest C14 galaxy. 4.3" from GALEXASC J102145.04+060829.3. (9) K2 Candidate. Located 2.3" from C14 galaxy SDSS J103704.22+132043.7 (EPICID=248903363). (10) Outside the C14 galaxy footprint. 3.8' from nearest C14 galaxy. Orphan - almost certainly a mover or chip crosstalk. No appearance on subsequent days. (11) Outside the C14 galaxy footprint. 13.4' from nearest C14 galaxy. Almost certainly stellar variable. (12) K2 candidate. Located 4.2" from C14 galaxy SDSS J104329.88+013225.7 (z=0.105869) (EPICID=248451937).
