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
S190701ah in a time range of 1000 seconds [3] centered
on the alert event time (2019-07-01 20:24:46.578 UTC to 2019-07-01
20:41:26.578 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 S190701ah
calculated from the map circulated in the 2-Initial 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 S190701ah ranges from  0.029 to 0.176 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
