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: SUM10R
- Serial Number: 841
- Issue Time: 2024 Oct 09 0431 UTC
- SUMMARY: 10cm Radio Burst
- Begin Time: 2024 Oct 09 0136 UTC
- Maximum Time: 2024 Oct 09 0203 UTC
- End Time: 2024 Oct 09 0400 UTC
- Duration: 174 minutes
- Peak Flux: 2700 sfu
- Latest Penticton Noon Flux: 225 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.

Space Weather Message Code: ALTPC0
- Serial Number: 52
- Issue Time: 2024 Oct 09 0408 UTC
- ALERT: Proton Event 100MeV Integral Flux exceeded 1pfu
- Begin Time: 2024 Oct 09 0350 UTC
- 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.
