Active Region 2415, now located at the center of the solar disk, erupted with moderately strong M1.1 solar flare at 09:40 UTC on September 17, 2015. The event started at 09:34, and ended at 09:45 UTC.
There were no radio signatures that would suggest a Coronal Mass Ejection (CME) was produced.
Region 2415, has beta-gamma magnetic configuration and is capable of producing strong eruptions on the Sun. CME's produced by this region should be Earth-directed.
The region is currently the largest region on the disk and it showed slight growth in overall coverage and its trailer spots since September 15.
SWPC forecasters expect solar activity to continue at moderate levels over the next three days (September 17 – 19) with a chance for M-class (R1-R2, Minor-Moderate) flares primarily due to the increased complexity of Region 2415.
