The IceCube Collaboration (http://icecube.wisc.edu/) reports:
IceCube has performed a search for track-like muon neutrino events arriving from the direction of SBS 1150+497 (ATel #13253) in a time window 2 days in duration (2019-10-30 00:00:01.0 UTC to 2019-10-31 23:59:59.0 UTC), during which IceCube was collecting good quality data. One track-like event is found in spatial coincidence with SBS 1150+497 during this time period. We find that these data are well described by atmospheric background expectations, with a p-value of 1.0. We accordingly derive a time-integrated muon-neutrino flux upper limit for this source of E^2 dN/ dE = 6.31 x 10^-5 TeV cm^-2 at 90% CL, under the assumption of an E^-2 power law. 90% of events IceCube would detect from a source at this declination with an E^-2 spectrum are between approximately 600 GeV and 300 TeV.
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.
