End Time: 2014 Sep 11 1525 UTC
Duration: 2 minutes

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.

Space Weather Message Code: SUM10R
Serial Number: 626
Issue Time: 2014 Sep 09 0028 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Sep 08 2349 UTC
Maximum Time: 2014 Sep 08 2352 UTC
End Time: 2014 Sep 08 2359 UTC
Duration: 10 minutes
Peak Flux: 370 sfu
Latest Penticton Noon Flux: 164 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.
