The event was \nselected by the ICECUBE_Astrotrack_Bronze alert stream.�� The average \nastrophysical neutrino purity for Bronze alerts is 30%. This alert has \nan estimated false alarm rate of 1.93events per year due to atmospheric \nbackgrounds. The IceCube detector was in a normal operating state at the \ntime of detection.\n\n\nAfter the initial automated alert \n(https://gcn.gsfc.nasa.gov/notices_amon_g_b/133634_1410505.amon), more\n\nsophisticated reconstruction algorithms have been applied offline, with \nthe direction refined to:\n\n\nDate: 20/01/17\n\nTime: 11:08:29.69UT\n\nRA: 116.24 (+0.71-1.24�� deg 90% PSF containment) J2000\n\nDec: 29.14�� (+0.90-0.78�� deg 90% PSF containment) J2000\n\n\nWe encourage follow-up by ground and space-based instruments to help \nidentify a possible astrophysical source for the candidate neutrino.\n\n\nThere are no 4FGL sources inside the 90% localization region. The \nclosest source is 4FGL J0746.5+2730 located at RA 116.63 deg and dec \n27.52 deg�� (at a distance of 1.66 degrees from the best-fit location).\n\n\nThe IceCube Neutrino Observatory is a cubic-kilometer neutrino detector \noperating at the geographic South Pole, Antarctica. The IceCube realtime \nalert point of contact can be reached at roc@icecube.wisc.edu\n\n*",
