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.

Location: S05W85
NOAA Scale: R3 - Strong

NOAA Space Weather Scale descriptions can be found at

SUMMARY: 10cm Radio Burst
Begin Time: 2024 Jul 16 1318 UTC
Maximum Time: 2024 Jul 16 1320 UTC
End Time: 2024 Jul 16 1326 UTC
Duration: 8 minutes
Peak Flux: 550 sfu
Latest Penticton Noon Flux: 233 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.
