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

Searches [1,2] for track-like muon neutrino events detected by IceCube
consistent with the sky
localization of gravitational-wave candidate S190602aq in a time range of
1000 seconds [3] centered
on the alert event time (2019-06-02 17:51:07.089 UTC to 2019-06-02
18:07:47.089 UTC) have been performed.  During this time
period IceCube was collecting good quality data.  No significant track-like
events are found
in spatial coincidence of S190602aq calculated from the map circulated in
the 1-Preliminary notice.

IceCube's sensitivity assuming an E^-2 spectrum (E^2 dN/dE)to neutrino
point sources within
the locations spanned by the 90% spatial  containment of S190602aq ranges
from  0.029 to
0.732 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. The IceCube realtime alert point of
contact can be
reached at roc at icecube.wisc.edu
