GCN Circular 24376

The IceCube Collaboration (http://icecube.wisc.edu/) reports:

IceCube has performed a search for track-like muon neutrino events
consistent with the sky localization of S190503bf in a time range of 1000
seconds centered on the alert event time (2019-05-03 18:45:44.294 UTC to 
2019-05-03 19:02:24.294 UTC)
during which IceCube was collecting good quality data.
No track-like events are found in spatial coincidence with the 90% 
spatial containment of S190503bf calculated from the map
circulated in the preliminary notice.

IceCube's sensitivity to point sources within the location spanned by 
the 90% spatial containment of S190503bf ranges from
0.227 to 0.821 GeV cm^-2 in a 1000 second time window.

The IceCube Neutrino Observatory is a cubic-kilometer neutrino detector 
operating at the geographic South Pole, Antarctica.
