Space Weather Message Code: SUM10R
Serial Number: 603
Issue Time: 2014 Jan 07 1054 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Jan 07 1011 UTC
Maximum Time: 2014 Jan 07 1012 UTC
End Time: 2014 Jan 07 1016 UTC
Duration: 5 minutes
Peak Flux: 409 sfu
Latest Penticton Noon Flux: 204 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.

ALERT: Proton Event 100MeV Integral Flux exceeded 1pfu
Begin Time: 2014 Jan 06 0835 UTC
Potential Impacts: An enhancement in the energetic portion of the solar radiation spectrum may indicate increased biological risk to astronauts or passengers and crew in high latitude, high altitude flights. Additionally, energetic particles may represent an increased risk to all satellite systems susceptible to single event effects. This information should be used in conjunction with the current Solar Radiation Storm conditions when assessing overall impact.
