Latest Penticton Noon Flux: 139 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.

SUMMARY: 10cm Radio Burst
Begin Time: 2025-06-15 17:55 UTC
Maximum Time: 2025-06-15 18:00 UTC
End Time: 2025-06-15 18:10 UTC
Duration: 15 minutes
Peak Flux: 1800 sfu
Latest Penticton Noon Flux: 151 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.
