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.

Space Weather Message Code: SUM10R
Serial Number: 776
Issue Time: 2024 Jan 29 0500 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2024 Jan 29 0408 UTC
Maximum Time: 2024 Jan 29 0420 UTC
End Time: 2024 Jan 29 0444 UTC
Duration: 36 minutes
Peak Flux: 2700 sfu
Latest Penticton Noon Flux: 141 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.
