Space Weather Message Code: SUM10R
Serial Number: 849
Issue Time: 2024 Nov 25 0821 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2024 Nov 25 0733 UTC
Maximum Time: 2024 Nov 25 0734 UTC
End Time: 2024 Nov 25 0736 UTC
Duration: 3 minutes
Peak Flux: 210 sfu
Latest Penticton Noon Flux: 203 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.

Potential Impacts: An enhancement in the energetic portion of the solar radiation spectrum may indicate increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights. Additionally, energetic particles may represent an increased risk to all satellite systems susceptible to single event effects. This information should be used in conjunction with the current Solar Radiation Storm conditions when assessing overall impact.
