The IceCube Collaboration (http://icecube.wisc.edu/) reports:
IceCube has performed a search for track-like muon neutrino events arriving from the position of Fermi J1153-1124 (http://www.astronomerstelegram.org/?read=12206) in a time window of 2 days (2018-11-10 00:00:00 UTC to 2018-11-13 00:00:00 UTC). 1 track event is found in spatial coincidence with Fermi J1153-1124 during this time period with a p-value of 0.019 (2.1 sigma) with respect to an atmospheric background only hypothesis. Accordingly, this event would represent a time-integrated muon-neutrino flux normalization upper limit assuming an E^-2 spectrum (E^2 dN/dE) at the 90% CL of 1.67 x 10^-4 TeV cm^-2 for this observation period.
The detected event, coincident with the source location within the track uncertainties for these events (~0.5 degrees), arrived at:
2018-11-11 07:41:30 UTC (MJD 58433.32048611)
While this detected event does not represent a significant detection, its arrival time is of potential interest to the astronomical community.
The IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica. The IceCube realtime alert point of contact can be reached at roc@icecube.wisc.edu.
