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: ALTTP4
- Serial Number: 670
- Issue Time: 2024 Oct 26 0725 UTC
- ALERT: Type IV Radio Emission
- Begin Time: 2024 Oct 26 0629 UTC
- Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.
Geophysical Alert Message Issued: Oct 26th, 2024 3:23:36 am
Space Weather Message Code: SUM10R
- Serial Number: 845
- Issue Time: 2024 Oct 26 0723 UTC
- SUMMARY: 10cm Radio Burst
- Begin Time: 2024 Oct 26 0618 UTC
- Maximum Time: 2024 Oct 26 0619 UTC
- End Time: 2024 Oct 26 0623 UTC
- Duration: 4 minutes
- Peak Flux: 270 sfu
- Latest Penticton Noon Flux: 209 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.

- Begin Time: 2024 Oct 26 0629 UTC
- Estimated Velocity: 486 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.
