Space Weather Message Code: SUMXM5 Serial Number: 324 Issue Time: 2026 Jul 05 1809 UTC SUMMARY: X-ray Event exceeded M5 Begin Time: 2026 Jul 05 1751 UTC Maximum Time: 2026 Jul 05 1757 UTC End Time: 2026 Jul 05 1802 UTC Xray Class: M5.5 Optical Class: Location: N15W87 Noaa Scale: R2 - Moderate Comment: NOAA Scale: R2 - Moderate NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation Potential Impacts: Area of impact centered primarily on sub-solar point on the sunlit side of Earth. Radio - Limited blackout of HF (high frequency) radio communication for tens of minutes.
Space Weather Message Code: ALTK04 Serial Number: 2671 Issue Time: 2026 Jul 05 1802 UTC ALERT: Geomagnetic K-index of 4 Threshold Reached: 2026 Jul 05 1759 UTC Synoptic Period: 1500-1800 Active Warning: YES Comment: NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation Potential Impacts: Area of impact primarily poleward of 65 degrees Geomagnetic Latitude. Induced Currents - Weak power grid fluctuations can occur. Aurora - Aurora may be visible at high latitudes such as Canada and Alaska.
Space Weather Message Code: ALTXMF Serial Number: 539 Issue Time: 2026 Jul 05 1800 UTC ALERT: X-Ray Flux exceeded M5 Threshold Reached: 2026 Jul 05 1758 UTC Noaa Scale: R2 - Moderate Comment: NOAA Scale: R2 - Moderate NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation Potential Impacts: Area of impact centered on sub-solar point on the sunlit side of Earth. Extent of blackout of HF (high frequency) radio communication dependent upon current X-ray Flux intensity.
