L’evento associato è stato di tipo II (con velocità stimata di 955 km/s) e di emissioni di tipo radio IV. Le emissioni di tipo IV si verificano in associazione a importanti eruzioni solari e sono in genere associate alla formazione di forti CME e tempeste di radiazioni solari.
La Regione 2443 classificata Beta-Delta si trova al centro del disco solare. La CME che ne è scaturita risulta diretta verso la Terra, con probabile arrivo stimato nella giornata del 7 novembre.
Dopo i brillamenti M1.9 e 2.5 scaturiti dalla Regione 2445, questo è il terzo brillamento solare di classe Media della giornata.

Space Weather Message Code: SUM10R
Serial Number: 675
Issue Time: 2015 Nov 04 1408 UTC
SUMMARY: 10cm Radio Burst
Begin Time: 2015 Nov 04 1338 UTC
Maximum Time: 2015 Nov 04 1341 UTC
End Time: 2015 Nov 04 1346 UTC
Duration: 8 minutes
Peak Flux: 290 sfu
Latest Penticton Noon Flux: 124 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.
