XM5A 2025-02-02 14:05:35.810

  • Issued: Sun, 02 Feb 2025 14:05:35 +0000
  • Space Weather Message Code: ALTXMF
    Serial Number: 470
    Issue Time: 2025 Feb 02 1405 UTC
    
    ALERT: X-Ray Flux exceeded M5
    Threshold Reached: 2025 Feb 02 1404 UTC
    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. For real-time information on affected area and expected duration please see http://www.swpc.noaa.gov/products/d-region-absorption-predictions-d-rap.

  • Space Weather Message Code: ALTTP2
    Serial Number: 1398
    Issue Time: 2025 Feb 02 1040 UTC
    
    ALERT: Type II Radio Emission
    Begin Time: 2025 Feb 02 1018 UTC
    Estimated Velocity: 664 km/s
    
    
    
    Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.
