M1.9 solar flare erupts from Sun’s central region 2422


Active Region 2422, located almost at the center of the solar disk, erupted with M1.9 solar flare at 10:40 UTC on September 27, 2015. The event started at 10:20 and ended at 10:46 UTC.

This region has 'Beta-Gamma-Delta' magnetic configuration and is capable of producing more strong to major eruption on the Sun. Its position makes it a perfect candidate for Earth-directed CME's in the days ahead.

At the time of press (11:09 UTC) there were no reports of radio signatures that would suggest a Coronal Mass Ejection (CME) was produced by this event.

There are currently 7 numbered sunspot regions on the Earth side of the Sun.

2423 – Beta
2424 – Beta
2425 – Beta
2426 – Beta

Region 2422 underwent consolidation and slight decay of a few of its intermediate spots late September 26. All other regions are relatively quiet and stable.

Regions 2411 and 2414 are due to return between September 27 and 29.

The geomagnetic field is currently at quiet levels.

Solar wind parameters are expected to be at nominal conditions from September 27 to 29.
