C9.9 Solar Flare Erupts From AR 2740, Strongest Since October 2017

C9.9 solar flare erupts from AR 2740, the strongest since October 2017

A moderately strong solar flare measuring C9.9 erupted from AR 2740 (Beta-Delta) at 05:10 UTC on May 6, 2019. The event started at 05:04 UTC and ended at 05:12 UTC. This is the strongest solar flare since M1.0 at 23:28 UTC on October 20, 2017.

A Type II Radio Emission with an estimated velocity of 740 km/s was associated with the event, suggesting a Coronal Mass Ejection (CME) was produced by the flare event.

The current position of this region does not favor Earth-directed flares.

Region 2740 was the source of several B and C-class solar flares over the past couple of days, but there were no Earth-directed CMEs produced.

It currently has Beta-Delta magnetic configuration and is capable of producing strong solar flares.

Earth-directed CMEs are possible in the days ahead as the region rotates into a geoeffective position.

This is the strongest solar flare in 2018 and 2019. The second strongest since January 1, 2018 was C8.1 at 13:47 UTC on February 7, 2018 and the third strongest C5.3 at 03:12 UTC on March 21, 2019.

Solar Cycle 24 produced a total of 49 X-class flares. The strongest was X9.3 at 12:02 UTC on September 6, 2017, followed by X8.2 at 16:06 UTC on September 10, 2017, X6.9 at 08:05 UTC on August 9, 2011, X5.4 at 00:24 UTC on March 7, 2012 and X4.9 at 00:49 UTC on February 25, 2014.
