GCN Circular 13287
Valerie Connaughton (UAH) and David Byrne (UCD) report on behalf of the Fermi GBM Team: "The event which triggered the Fermi Gamma-ray Burst Monitor at 17:46:57 UT on 10 May 2012 (120510741/358364818) is not a GRB. This event was classified as being of uncertain origin by the GBM Flight Software owing to an inability to localize it on-board. Inspection of the data suggests that this event is of solar origin, correlating in time with a C-class solar flare seen in the GOES data. On-ground localization using the GBM data places the event within 2 deg of the Sun. The OT reported by Gorbovskoy et al. (GCN 13285) is thus not related to Fermi GBM trigger 358364818."
