Fermi GBM detected a gamma-ray burst with unreliable localization on 2026-10-15
AI Summary
Fermi GBM triggered on a gamma-ray transient at 2026-10-15T14:01:05.78Z (TrigID 813765670) with a burst intensity of 511 and significance of 5.8σ over 64ms timescale. The event was classified as 'Unreliable_Location' with 100% confidence, indicating poor localization quality with a 30.5° error radius centered at RA=235.48°, Dec=48.45°. The burst was detected in the 23-47 keV energy range across 40 detectors with delayed transmission flags, suggesting this is a low-confidence trigger unsuitable for immediate follow-up observations.
