3rd X-class solar flare: Major X1.3 flare erupts from Region 2673, CME produced
A major solar flare measuring X1.3 at its peak time erupted from Region 2673 at 14:36 UTC on September 7, 2017. The event started at 14:20, peaked at 14:36 and ended at 14:55 UTC. This is the third X-class solar flare since X2.2 at 09:10 UTC and X9.3 at 12:02 UTC on September 6.
The event was associated with a 10cm Radio Burst lasting 7 minutes with peak flux of 1600 sfu. 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.
In addition, a CME signature first observed in SOHO/LASCO C2 imagery at 15:12 UTC and a Type II radio sweep were associated with this event.
