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 Feb 28 1506 UTC
Maximum Time: 2025 Feb 28 1514 UTC
End Time: 2025 Feb 28 1530 UTC
Duration: 24 minutes
Peak Flux: 380 sfu
Latest Penticton Noon Flux: 153 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.
