SUMMARY: 10cm Radio Burst
Begin Time: 2024-07-27 05:37 UTC
Maximum Time: 2024-07-27 05:39 UTC
End Time: 2024-07-27 05:43 UTC
Duration: 6 minutes
Peak Flux: 320 sfu
Latest Penticton Noon Flux: 176 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.
