Rest (STScI)\n\nReport several transients discovered in and around the \nRA=1hr DEC=+4deg error region as defined in the BAYESTAR \nskymap.fits file. \n\nThis area has been covered in the w and i-bands \nduring the routine course of the Pan-STARRS Survey for Transients\n(see Huber et al. 2015, ATel 7153 and http://star.pst.qub.ac.uk/ps1threepi/psdb/)\nand around 10 supernova candidates are known from the last \n7 days of observations in this region. These are almost certainly all \nunrelated to the GW trigger, as they were discovered days before the \nLIGO/Virgo detection. Details are available on the public webpage above. \n\nFor example, the most recent discovery is a i=18.6 supernova candidate at \n7.2��� from the core of MCG -01-59-024 at z=0.033. This was discovered on 57315.31, \n54h before the GW trigger (at position 23:28:24.29 -02:47:57.8)\n\nPan-STARRS was observing the RA=1hr localisation region (south of dec=0), \nduring the night of 2015-10-22. However the observations were taken 5-6hrs\nbefore the LIGO/Virgo detection. Difference imaging and transient searches\nare underway and further observations are planned for the \ncoming nights. We plan to cover this RA=1hr region with the PS1 1.8m\ntelescope, 7 sq degree camera, in i and z bands.",
