A major solar flare measuring X1.6 at its peak time erupted from Region 2192 on October 22, 2014. The event started at 14:02, peaked at 14:28 and ended at 14:50 UTC.
R3 - Strong radio blackout produced significant HF signal fading on the sunlit side of Earth. There are about 175 such events during each solar cycle, according to NOAA.
A 10cm Radio Burst (4 min/200 sfu) was associated with the event. 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.
This is a second X-class (the strongest) solar flare in the last 3 days, after
