Major, long-duration X1.1 solar flare erupts, producing full halo CME - March 23, 2024

A major, long-duration solar flare measuring X1.1 erupted from Active Region 3614 (provisional) at 01:33 UTC on March 23, 2024. The event started at 00:58 and ended at 02:21 UTC. A full halo CME was produced, with impacts to Earth likely late March 25 or early March 26. A Type II Radio Emission with an estimated velocity of 791 km/s was associated with the event -- indicating a coronal mass ejection (CME) was produced. In addition, a 10cm Radio Burst (tenflare) lasting 66 minutes and with a peak flux of 240 sfu was also associated with this event. 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. The event produced a full halo CME and part of it is likely Earth-directed. “This could easily give us G2, possibly G3-level impacts, sometime late March 25 or early March 26,“ Dr. Tamitha Skov said. “Waiting for NASA and NOAA models to confirm,“ Skov added.
