TIIA 2025-01-22 11:50:46.053

  • Issued: Wed, 22 Jan 2025 11:50:46 +0000
  • Space Weather Message Code: ALTTP2
    Serial Number: 1391
    Issue Time: 2025 Jan 22 1150 UTC
    
    ALERT: Type II Radio Emission
    Begin Time: 2025 Jan 22 1058 UTC
    Estimated Velocity: 561 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.
