Cline,\non behalf of the Konus-Wind team, report:\n\nKonus-Wind (KW) was observing the whole sky between the last\nGOTO non-detection (2023-06-17 23:50:30 UTC, hereafter T1; \nGompertz at al., GCN Circ. 34023) and the first GOTO detection\n(2023-06-18 01:27:41 UTC, hereafter T2; Gompertz at al., GCN Circ. 34023)\nof ZTF23aaoohpy/AT2023lcr/ATLAS23msn (Swain et al., GCN Circ. 34022;\nTonry et al. TNS Astronomical Transient Report No. 180429).\n\nNo triggered or waiting-mode KW GRBs were detected during the\ninterval from T1 to T2. The closest waiting-mode GRBs were observed\n~6.5 hours before T1 and ~2.3 hours after T2.\n\nFor the interval from T1 to T2, we estimate an upper limit (90% conf.)\non the 20 - 1500 keV fluence to 6.5x10^-7 erg/cm^2 for a burst lasting\nless than 2.944 s and having a typical KW short GRB spectrum \n(an exponentially cut off power law with alpha =-0.5 and Ep=500 keV). \nFor a typical long GRB spectrum (the Band function with alpha=-1, \nbeta=-2.5, and Ep=300 keV), the corresponding limiting peak flux \nis 1.8x10^-7 erg/cm^2/s (20 - 1500 keV, 2.944 s scale).\n\nAll the quoted values are preliminary.",
