Y. Lien et al., GCN 32874) errorbox 17090 sec after notice time and 17113 sec after trigger time at 2022-10-28 18:01:41 UT, with upper limit up to 18.7 mag. Observations started at twilight. The observations began at zenith distance = 74 deg. The sun altitude is -13.0 deg. The galactic latitude b = -3 deg., longitude l = 83 deg.
