A major, long-duration solar flare measuring X1.1 erupted from a large, geoeffective Active Region 3784 at 06:40 UTC on August 14, 2024. The event started at 06:00 and ended at 07:08 UTC.
This event was associated with a Type II Radio Emission (estimated velocity 223 km/s) and a Type IV emission, suggesting a strong coronal mass ejection (CME) was produced.
Additionally, a 10cm Radio Burst lasting 14 minutes and with peak flux of 500 sfu was registered from 06:41 to 06:55 UTC. 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.
Radio emissions were forecast to be most degraded over East Africa, Middle East, Asia, and the Indian Ocean at the time of the flare.
The location of this region, at the center of the solar disk, suggests an Earth-directed CME was produced.
Region 3784 has ‘beta-gamma-delta’ magnetic configuration and is capable of producing more major eruptions in the days ahead. Additional Earth-directed CMEs are possible from this region.
