Impulsive solar flare measuring M6.3 erupted on November 1, 2013 at 19:53 UTC. The source of this event is centered around AR 1884 located at the center of disk and very geoeffective.

A 10 cm Radio Burst (TenFlare) was associated with the event. 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: 2013 Nov 01 1949 UTC
Maximum Time: 2013 Nov 01 1950 UTC
End Time: 2013 Nov 01 1953 UTC
Duration: 4 minutes
Peak Flux: 280 sfu
Latest Penticton Noon Flux: 143 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.
