An impulsive solar flare measuring X1.3 erupted from an unnumbered active region on the SE limb of the Sun at 09:43 UTC on September 12.<\/p>\n
Associated with this event were multiple discrete radio bursts and a 10cm Radio Burst (tenflare) lasting 2 minutes with a peak flux of 240 sfu.<\/p>\n
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.<\/p>\n
Radio frequencies were forecast to be most degraded over Africa and parts of Europe and Asia at the time of the flare.<\/p>\n
\u201cFlares of this magnitude in and around solar maximum are generally not common, although not necessarily unusual,\u201d SWPC forecasters said.<\/p>\n
A coronal mass ejection (CME) was most likely produced by this event, but the region is still not in a location that favors Earth-directed CMEs. This will change in the week ahead.<\/p>\n \n
