RA(J2000) = 18h 16m 36s Dec(J2000) = +74d 42' 50"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a multi-peaked structure with a duration of about 10 sec. The peak count rate was ~3000 counts/sec (15-350 keV), at ~0 sec after the trigger.

UL gives the 5 sigma upper limit sensitivity in magnitudes, for images co-added to the given exposure time. The first row in the table corresponds to co-adds of an initial short exposure image sequence of 1 s (these sub-second exposures are read-noise suppressed by our EMCCD cameras, with high gain electron multiplication active; other images are taken in conventional CCD operation mode) for r'. The second row corresponds to co-adds from a continuing series of 15 s exposures for g' and r’. Calibration was done with 3 Pan-STARRS catalog stars on our images. No color or other corrections were applied to the values above.
