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: May 30th, 2023 11:09:05 am
Space Weather Message Code: SUM10R
- Serial Number: 761
- Issue Time: 2023 May 30 1109 UTC
- SUMMARY: 10cm Radio Burst
- Begin Time: 2023 May 30 1020 UTC
- Maximum Time: 2023 May 30 1020 UTC
- End Time: 2023 May 30 1020 UTC
- Duration: 1 minutes
- Peak Flux: 210 sfu
- Latest Penticton Noon Flux: 154 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.
