Having SatCom problems?
A burst of radiation on the sun's surface may trigger a geomagnetic storm, which can disrupt satellite communications.
In order to prevent unnecessary maintenance on satellite communications systems Air Sat One has provided a feed of Geophysical Events from NOAA's Space Weather Prediction Center. Check here to see if solar activity could be a cause of satellite communications problems.

Space Weather Message Code: WARPC0
- Serial Number: 116
- Issue Time: 2024 Nov 22 0950 UTC
- CANCEL WARNING: Proton 100MeV Integral Flux above 1pfu expected
- Cancel Serial Number: 115
- Original Issue Time: 2024 Nov 21 1900 UTC
- Comment: 100MeV proton flux has steadily decreased and is anticipated to remain below the 1 pfu threshold barring another event.
- NOAA Space Weather Scale descriptions can be found at
- www.swpc.noaa.gov/noaa-scales-explanation
- Potential Impacts: An enhancement in the energetic portion of the solar radiation spectrum may indicate increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights. Additionally, energetic particles may represent an increased risk to all satellite systems susceptible to single event effects. This information should be used in conjunction with the current Solar Radiation Storm conditions when assessing overall impact.
