Space Weather Message Code: SUM10R
Serial Number: 784
Issue Time: 2024 Feb 22 2341 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2024 Feb 22 2224 UTC
Maximum Time: 2024 Feb 22 2225 UTC
End Time: 2024 Feb 22 2235 UTC
Duration: 11 minutes
Peak Flux: 240 sfu
Latest Penticton Noon Flux: 173 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.
