GOES (Gp16) satellite energetic Proton Flux (Courtesy of SWPC, Boulder Colorado, USA) Proton event detection will lag data time by approximately 1 hour due to data smoothing. Data Date/Time: 21 12 2024 1210 UT Proton Energy Current Proton Level Flux Event Status 10MeV 2.46e+00PFU No proton event in progress 100MeV 2.07e-01PFU No proton event in progress 500MeV 1.84e-01PFU No proton event in progress Units: PFU = protons/cm2/sec/ster MeV = million electron volts Proton energy levels and PFU event thresholds: Proton Energy Proton Flux Level Threshold 10MeV 10PFU 100MeV 1PFU 500MeV 1PFU Gp: GOES primary Gs: GOES secondary Solar proton events can impact satellite operations and transpolar HF communications.
