Space Weather Message Code: SUM10R
Serial Number: 612
Issue Time: 2014 Feb 25 0129 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Feb 25 0042 UTC
Maximum Time: 2014 Feb 25 0045 UTC

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.

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: 608
Issue Time: 2014 Feb 02 1825 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Feb 02 1809 UTC
Maximum Time: 2014 Feb 02 1809 UTC
End Time: 2014 Feb 02 1810 UTC
Duration: 1 minutes
Peak Flux: 180 sfu
Latest Penticton Noon Flux: 177 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.
