End Time: 2022 Nov 07 0016 UTC
X-ray Class: M5.2

NOAA Scale: R2 - Moderate
Potential Impacts: Area of impact centered primarily on sub-solar point on the sunlit side of Earth.
Radio - Limited blackout of HF (high frequency) radio communication for tens of minutes.

SUMMARY: 10cm Radio Burst
Begin Time: 2022 Nov 07 0005 UTC
Maximum Time: 2022 Nov 07 0006 UTC
End Time: 2022 Nov 07 0008 UTC
Duration: 3 minutes
Peak Flux: 740 sfu
Latest Penticton Noon Flux: 131 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.
