FROM:    Rachel Dunwoody at UCD  <rachel.dunwoody@ucdconnect.ie>

R. Dunwoody (UCD) and J.Mangan (CNRS/IJCLab) report on behalf of the
Fermi-GBM team:

"The Fermi Gamma-ray Burst Monitor (GBM) trigger 230208382/697540213 at
09:10:08.92 UT
on 08 February 2023, tentatively classified as a GRB, is in fact not due to
a GRB.
This trigger is likely due to LS V +44 17 / RX J0440.9+4431.

We anticipate GBM will trigger further on flares from LS V +44 17 / RX
J0440.9+4431 while
the source is still active, some of which may be misclassified as GRBs. We
will not be reporting
on those triggers from this region of the sky."
