TIIA 2024-05-15 15:08:40.440

  • Issued: Wed, 15 May 2024 15:08:40 +0000
  • Space Weather Message Code: ALTTP2
    Serial Number: 1301
    Issue Time: 2024 May 15 1508 UTC
    
    ALERT: Type II Radio Emission
    Begin Time: 2024 May 15 1427 UTC
    Estimated Velocity: 1064 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.                                

XM5A 2024-05-15 14:27:45.383

  • Issued: Wed, 15 May 2024 14:27:45 +0000
  • Space Weather Message Code: ALTXMF
    Serial Number: 385
    Issue Time: 2024 May 15 1427 UTC
    
    ALERT: X-Ray Flux exceeded M5
    Threshold Reached: 2024 May 15 1424 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.                                

P12S 2024-05-15 13:29:30.380

  • Issued: Wed, 15 May 2024 13:29:30 +0000
  • Space Weather Message Code: SUMPX2
    Serial Number: 51
    Issue Time: 2024 May 15 1329 UTC
    
    SUMMARY: Proton Event 10MeV Integral Flux exceeded 100pfu
    Begin Time: 2024 May 14 0315 UTC
    Maximum Time: 2024 May 14 0505 UTC
    End Time: 2024 May 14 0650 UTC
    Maximum 10MeV Flux: 121 pfu
    NOAA Scale: S2 - Moderate

BHIS 2024-05-15 11:49:56.247

  • Issued: Wed, 15 May 2024 11:49:56 +0000
  • Space Weather Message Code: SUM10R
    Serial Number: 804
    Issue Time: 2024 May 15 1149 UTC
    
    SUMMARY: 10cm Radio Burst
    Begin Time: 2024 May 15 1039 UTC
    Maximum Time: 2024 May 15 1044 UTC
    End Time: 2024 May 15 1048 UTC
    Duration: 9 minutes
    Peak Flux: 250 sfu
    Latest Penticton Noon Flux: 220 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.                                

XX0S 2024-05-15 09:05:59.043

  • Issued: Wed, 15 May 2024 09:05:59 +0000
  • Space Weather Message Code: SUMX01
    Serial Number: 157
    Issue Time: 2024 May 15 0905 UTC
    
    SUMMARY: X-ray Event exceeded X1
    Begin Time: 2024 May 15 0818 UTC
    Maximum Time: 2024 May 15 0837 UTC
    End Time: 2024 May 15 0852 UTC
    X-ray Class: X3.4
    Optical Class: na
    Location: S22W90
    NOAA Scale: R3 - Strong
    
    NOAA Space Weather Scale descriptions can be found at
    www.swpc.noaa.gov/noaa-scales-explanation
    
    Potential Impacts: Area of impact consists of large portions of the sunlit side of Earth, strongest at the sub-solar point.
    Radio - Wide area blackout of HF (high frequency) radio communication for about an hour.
