  "body": "The IceCube Collaboration (http://icecube.wisc.edu/) reports:\n\nIceCube has performed a search for track-like muon neutrino events arriving \nfrom the direction of HAWC Burst Alert 1008846_957 (GCN 25284) in a time \nwindow 12 hours in duration centered on the burst time (2019-08-06 07:20:48.0 UTC \nto 2019-08-06 19:20:48.0 UTC), during which IceCube was collecting good quality data. \nZero track-like events are found in spatial coincidence with the location of the HAWC \nalert during this time period. Accordingly, the time-integrated muon-neutrino flux, \nmultiplied by E^2, upper limit at the alert position assuming an E^-2 spectrum (E^2 dN/dE) \nat the 90% CL is 3.53 x 10^-5 TeV cm^-2 for this observation period. 90% of events \nIceCube would detect from a source at this declination with an E^-2 spectrum \nare between approximately 1 TeV and 3 PeV.\n\nThe IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating \nat the geographic South Pole, Antarctica. The IceCube realtime alert point of contact \ncan be reached at roc@icecube.wisc.edu.",
