MSG 5 - Date: 2024-04-23 03:57:12.847
Space Weather Message Code: SUM10R
Serial Number: 789
Issue Time: 2024 Apr 23 0357 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2024 Apr 23 0313 UTC
Maximum Time: 2024 Apr 23 0314 UTC
End Time: 2024 Apr 23 0315 UTC
Duration: 2 minutes
Peak Flux: 290 sfu
Latest Penticton Noon Flux: 227 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.
