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.

    We are in deep solar minimum, but a huge sunspot, twice as wide as Earth (sunspot AR 2740) has formed on the surface of the Sun and another big sunspot is now emerging over the eastern limb. At the same time, solar wind flowing from A large coronal hole should reach Earth on May 8th.
