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 S190630ag in a time range of
1000 seconds [3] centered
on the alert event time (2019-06-30 18:43:45.180 UTC to 2019-06-30
19:00:25.180 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 S190630ag 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 S190630ag ranges
from  0.029 to
0.977 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
