Sunspot region 2628

Our Sun is showing signs of life this morning as it produced two strong C-class solar flares.

It was sunspot region 2628 that produced an C9.3 solar flare at 07:26 UTC and an C6.1 solar flare at 11:08 UTC as you can see here on our solar flares page. The solar flares were impulsive and no coronal mass ejections were launched into space.

It is however an interesting sunspot region to keep an eye on in the days ahead especially now that we are in a period with very little solar activity. Up until today we had only one C-class solar flare this year! Sunspot region 2628 is an emerging sunspot region on the Sun's eastern hemisphere so if it continues to develop in the days ahead it might be in an earth-facing position when it lets loose a big solar flare.

But fair enough, that is just speculation at the moment as it is still a fairly simple sunspot region that we didn't really think would be capable of producing high-level C-class events. There is some magnetic mixing potential near its leader spot but it is not that complex yet. It is a Beta region, but a Beta region with potential. A low-level (R1) M-class solar flare does not seem likely but considering it already produced a C9 event, we should not exclude it. A bit more growth and magnetic mixing wouldn't hurt if we want to see strong solar flares but it is well worth keeping an eye on this region in the days ahead!

Current data suggest that it is not possible to see aurora now at middle latitudes
The solar wind speed is currently moderately high (533 km/sec.)
