The reconstructed origin was -7 degrees below the horizon for ANTARES.\n\nNo up-going muon neutrino candidate events were recorded within 90% error box of the IceCube event during a +/- 1h time-window centered on the IceCube event time, and over which the potential source remained visible all time. This leads to a preliminary 90% confidence level upper limit on the muon-neutrino fluence from a point source of 17.1 GeV.cm^-2 over the energy range 3.2 TeV - 3.5 PeV (the range corresponding to 5-95% of the detectable flux) for an E^-2 power-law spectrum, and 68.3 GeV.cm^-2 (640 GeV - 325 TeV) for an E^-2.5 spectrum. A search over an extended time window of +/- 1 day has also yielded no detection (49% visibility).\nANTARES <http://antares.in2p3.fr/> is the largest undersea neutrino detector (Mediterranean Sea) and it is primarily sensitive to astrophysical neutrinos in the TeV-PeV energy range. At 10 TeV, the median angular resolution for muon neutrinos is about 0.5 degrees. In the range 1-100 TeV ANTARES has a competitive sensitivity to this position in the sky.",
