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.
Geophysical Alert Message Issued: Dec 8th, 2024 4:25:32 am
Space Weather Message Code: ALTTP2
- Serial Number: 1380
- Issue Time: 2024 Dec 08 0925 UTC
- ALERT: Type II Radio Emission
- Begin Time: 2024 Dec 08 0905 UTC
- Estimated Velocity: 626 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.
Geophysical Alert Message Issued: Dec 8th, 2024 4:28:24 am
Space Weather Message Code: SUMX01
- Serial Number: 182
- Issue Time: 2024 Dec 08 0928 UTC

Geophysical Alert Message Issued: Dec 8th, 2024 4:21:46 am
Space Weather Message Code: SUM10R
- Serial Number: 850
- Issue Time: 2024 Dec 08 0921 UTC
- SUMMARY: 10cm Radio Burst
- Begin Time: 2024 Dec 08 0903 UTC
- Maximum Time: 2024 Dec 08 0904 UTC
- End Time: 2024 Dec 08 0906 UTC
- Duration: 3 minutes
- Peak Flux: 870 sfu
- Latest Penticton Noon Flux: 183 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: 454
- Issue Time: 2024 Dec 08 0906 UTC
- ALERT: X-Ray Flux exceeded M5
- Threshold Reached: 2024 Dec 08 0905 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.
