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: Jul 27th, 2024 2:00:31 am
Space Weather Message Code: ALTTP2
- Serial Number: 1328
- Issue Time: 2024 Jul 27 0600 UTC
- ALERT: Type II Radio Emission
- Begin Time: 2024 Jul 27 0434 UTC
- Estimated Velocity: 251 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: Jul 27th, 2024 2:04:32 am
Space Weather Message Code: SUM10R
- Serial Number: 816
- Issue Time: 2024 Jul 27 0604 UTC
- SUMMARY: 10cm Radio Burst
- Begin Time: 2024 Jul 27 0537 UTC
- Maximum Time: 2024 Jul 27 0539 UTC
- End Time: 2024 Jul 27 0543 UTC
- Duration: 6 minutes
- Peak Flux: 320 sfu
- Latest Penticton Noon Flux: 176 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.
