C. Malacaria (ISSI) and P. Veres (UAH) report on behalf of the Fermi-GBM Team:

"The Fermi Gamma-ray Burst Monitor (GBM) trigger 230203275 / 697098930 at
06:35:25.27 UT on 03 February 2023, tentatively classified as a GRB, is in
fact not due to a GRB. This trigger is likely due to LSV+44, a source
that has been recently
brightening and will likely produce more triggers in the following days."
