BHIS 2025-02-25 12:32:50.540

  • Issued: Tue, 25 Feb 2025 12:32:50 +0000
  • Space Weather Message Code: SUM10R
    Serial Number: 861
    Issue Time: 2025 Feb 25 1232 UTC
    
    SUMMARY: 10cm Radio Burst
    Begin Time: 2025 Feb 25 1136 UTC
    Maximum Time: 2025 Feb 25 1137 UTC
    End Time: 2025 Feb 25 1149 UTC
    Duration: 13 minutes
    Peak Flux: 230 sfu
    Latest Penticton Noon Flux: 203 sfu
    
    
    
    Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.                                

TIVA 2025-02-25 12:31:39.633

  • Issued: Tue, 25 Feb 2025 12:31:39 +0000
  • Space Weather Message Code: ALTTP4
    Serial Number: 678
    Issue Time: 2025 Feb 25 1231 UTC
    
    ALERT: Type IV Radio Emission
    Begin Time: 2025 Feb 25 1139 UTC
    
    
    
    Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.                                

TIIA 2025-02-25 12:31:11.163

  • Issued: Tue, 25 Feb 2025 12:31:11 +0000
  • Space Weather Message Code: ALTTP2
    Serial Number: 1404
    Issue Time: 2025 Feb 25 1231 UTC
    
    ALERT: Type II Radio Emission
    Begin Time: 2025 Feb 25 1145 UTC
    Estimated Velocity: 630 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.                                

P11W 2025-02-25 11:49:07.823
