Major X1.1 Solar Flare | June 20, 2023

A major solar flare reaching a peak of X1.1 erupted from Active Region 13341 at 17:09 UTC on June 20. 

A Type II radio emission with an estimated velocity of 1027 km/s was registered at 17:01 UTC. Type II emissions occur in association with eruptions on the Sun and typically indicate a coronal mass ejection (CME) is associated with a flare event.

A Type IV radio emission was also associated with the event, suggesting a strong CME and solar radiation storm, as well as a 10cm Radio Burst lasting 16 minutes with a peak flux of 480 sfu.

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.

This eruptive X1.1 Solar Flare a strong CME was associated with this event however the location of this region is just on the eastern limb and most of the ejecta would likely be directed well away from Earth and will not be geoeffective.
