Space Weather Message Code: SUMXM5
Serial Number: 129
Issue Time: 2014 Nov 16 1821 UTC

SUMMARY: X-ray Event exceeded M5
Begin Time: 2014 Nov 16 1735 UTC
Maximum Time: 2014 Nov 16 1748 UTC
End Time: 2014 Nov 16 1757 UTC
X-ray Class: M5.7
Location: S12E46
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.


Space Weather Message Code: SUM10R
Serial Number: 646
Issue Time: 2014 Nov 16 1802 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Nov 16 1744 UTC
Maximum Time: 2014 Nov 16 1745 UTC
End Time: 2014 Nov 16 1745 UTC
Duration: 1 minutes
Peak Flux: 300 sfu
Latest Penticton Noon Flux: 161 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.

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Nov 07 1749 UTC
Maximum Time: 2014 Nov 07 1751 UTC
End Time: 2014 Nov 07 1800 UTC
Duration: 11 minutes
Peak Flux: 560 sfu
Latest Penticton Noon Flux: 136 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.
