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 on late March 25 or early March 26.<\/strong><\/p>\n

A Type II Radio Emission with an estimated velocity of 791 km\/s was associated with the event \u2014 indicating a coronal mass ejection (CME) was produced.<\/p>\n

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.<\/p>\n

The event produced a full halo CME and part of it is likely Earth-directed. \u201cThis could easily give us G2, possibly G3-level impacts, sometime late March 25 or early March 26,\u201d Dr. Tamitha Skov said. \u201cWaiting for NASA and NOAA models to confirm,\u201d Skov added.<\/p>\n

Radio frequencies were forecast to be most degraded over Japan, the Philippines, Indonesia, Australia, and New Zealand at the time of the flare.<\/p>\n

The flare was still in progress when a solar filament erupted near Region 3615, producing what might be an M-class event.<\/p>\n

It\u2019s worth noting that SWPC forecasters initially said it\u2019s hard to say with certainty which region [3615 or 3614] was the source of X flare, but the flare from 3614 appears to have a likely coronal mass ejection (CME) associated with it. \u201cWe must await imagery to be sure and begin analysis accordingly.\u201d<\/p>\n

In the reviewed solar flare events list for the day, SWPC attributed the X-class flare to Active Region 3614 (beta).<\/p>\n

Both regions are in geoeffective positions, suggesting any CME they produce today and over the next couple of days would be Earth-directed.<\/p>\n

Proton flux levels started sharply rising following this activity (at 03:50 UTC) and are now approaching the S1 \u2013 Minor solar radiation storm threshold. As a result, an S1 \u2013 Minor solar radiation storm watch is in effect through 21:00 UTC today.<\/p>\n

Furthermore, a G1 \u2013 Minor geomagnetic storm is currently in progress. Additional enhancements are likely on March 24 from the anticipated co-rotating interaction region (CIR) ahead of a negative polarity coronal hole high speed stream (CH HSS), with isolated periods of G1 \u2013 Minor storming likely on March 25.<\/p>\n
