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: SUMXM5
- Serial Number: 290
- Issue Time: 2025 May 25 1646 UTC
- SUMMARY: X-ray Event exceeded M5
- Begin Time: 2025 May 25 1618 UTC

- End Time: 2025 May 25 1636 UTC
- X-ray Class: M8.9
- Location: S04W53
- NOAA Scale: R2 - Moderate
- NOAA Space Weather Scale descriptions can be found at

Space Weather Message Code: SUM10R
- Serial Number: 868
- Issue Time: 2025 May 25 1641 UTC
- SUMMARY: 10cm Radio Burst
- Begin Time: 2025 May 25 1628 UTC
- Maximum Time: 2025 May 25 1629 UTC
- End Time: 2025 May 25 1630 UTC
- Duration: 2 minutes
- Peak Flux: 160 sfu
- Latest Penticton Noon Flux: 130 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: ALTXMF
- Serial Number: 484
- Issue Time: 2025 May 25 1631 UTC
- ALERT: X-Ray Flux exceeded M5
- Threshold Reached: 2025 May 25 1630 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.
