DONKI: View SW Activity

Solar Energetic Particle
Catalog: M2M_CATALOG
Event Time: 2026-01-18T22:55Z ( GOES-P: SEISS >10 MeV )
Activity ID: 2026-01-18T22:55:00-SEP-001 (version 2)
Note: M1.1 flare from AR 14345 peaking at 2026-01-19T11:19Z may have contributed further to this event that is mainly associated with the X1.9 flare and resulting CME from AR 14341, with a brief notable spike in all GOES-P energy channels (except >500 MeV) spanning approximately 2026-01-19T11:15Z to 2026-01-19T12:20Z. GOES >100 MeV protons rose from background to a peak value of 0.545 at 2026-01-19T11:40Z before settling back to background.
