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: Jun 15th, 2025 2:41:24 pm
Space Weather Message Code: ALTTP2
- Serial Number: 1418
- Issue Time: 2025 Jun 15 1841 UTC
- ALERT: Type II Radio Emission
- Begin Time: 2025 Jun 15 1819 UTC
- Estimated Velocity: 397 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.

Space Weather Message Code: SUM10R
- Serial Number: 873
- Issue Time: 2025 Jun 15 1825 UTC
- SUMMARY: 10cm Radio Burst
- Begin Time: 2025 Jun 15 1755 UTC
- Maximum Time: 2025 Jun 15 1800 UTC
- End Time: 2025 Jun 15 1810 UTC
- Duration: 15 minutes
- Peak Flux: 1800 sfu
- Latest Penticton Noon Flux: 151 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.
