The event comes just 4 days after X9.0 \u2014 thus far the strongest solar flare of Solar Cycle 25, also from Region 3842.<\/p>\n

The event was associated with a 10cm Radio Burst (tenflare) lasting 4 minutes and with a peak flux of 640 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

At the time of press, there were no radio signatures that would suggest a coronal mass ejection (CME) was produced. Even if it was, the location of this region now close to the west limb does not favor Earth-directed CMEs.<\/p>\n

Radio frequencies were forecast to be most degraded\u00a0over the Pacific Ocean at the time of the flare.\u00a0<\/p>\n
