Fermi GBM trigger 795185313 was initially misclassified as a GRB but later determined to be an accidental trigger.

AI Summary

The initial alert indicated a potential GRB, prompting follow-up observations by the MASTER-OAFA telescope which set upper limits on the brightness. However, it was subsequently confirmed that the trigger was not associated with a real GRB event.
