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: Feb 6th, 2025 7:49:33 am
Space Weather Message Code: SUMXM5
- Serial Number: 285
- Issue Time: 2025 Feb 06 1249 UTC
- SUMMARY: X-ray Event exceeded M5
- Begin Time: 2025 Feb 06 1047 UTC
- Maximum Time: 2025 Feb 06 1104 UTC
- End Time: 2025 Feb 06 1116 UTC
- X-ray Class: M7.6
- Location: N07W17
- NOAA Scale: R2 - Moderate
- Comment: Tenflare at 06/1058 with peak 8100 sfu
- NOAA Space Weather Scale descriptions can be found at
- www.swpc.noaa.gov/noaa-scales-explanation

Geophysical Alert Message Issued: Feb 6th, 2025 6:11:16 am
Space Weather Message Code: SUM10R
- Serial Number: 859
- Issue Time: 2025 Feb 06 1111 UTC
- SUMMARY: 10cm Radio Burst
- Begin Time: 2025 Feb 06 1058 UTC
- Maximum Time: 2025 Feb 06 1058 UTC
- End Time: 2025 Feb 06 1058 UTC
- Duration: 1 minutes
- Peak Flux: 8100 sfu
- Latest Penticton Noon Flux: 191 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.

- Threshold Reached: 2025 Feb 06 1113 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.
