Cline,\non behalf of the Konus-Wind team, report:\n\nUsing Konus-Wind (KW) data, we have performed a search for\na gamma-ray transient around the time of the cosmic neutrino\ncandidate IceCube-171106A (2017-11-06 18:39:39.21 UT,\nhereafter T0; Taboada, GCN 22105;\nhttps://gcn.gsfc.nasa.gov/notices_amon/17569642_130214.amon)\n\nNo triggered KW event happened from ~6.7 hours before and up to ~1.8 \ndays\nafter T0. The closest waiting-mode event was ~7.7 hours before T0.\nUsing waiting-mode data within the interval T0  +/- 1000 s,\nwe found no significant (> 5 sigma) excess over the background\nin both KW detectors on temporal scales from 2.944 s to 100 s in the \n80-1000 keV band.\nSignificant variations in the 20-80 keV band is due to activity of Swift \nJ0243+61.\n\nWe estimate an upper limit (90% conf.) on the 10 keV ��� 10 MeV fluence\nto 9.0x10^-7 erg/cm^2 for a burst lasting less than 2.944 s and having a\ntypical KW short GRB spectrum (an exponentially cut off power law with\nalpha =-0.5 and Ep=500 keV). For a typical long GRB spectrum (the Band\nfunction with alpha=-1, beta=-2.5, and Ep=300 keV), the corresponding\nlimiting peak flux is 3.1x10^-7 erg/cm^2/s (10 keV - 10 MeV, 2.944 s \nscale).\n\nAll the quoted values are preliminary.",
