We admit! We have been ignoring sunspot region 2674 since it appeared on the solar disk a few days ago. It was a large sunspot region at the time with two massive sunspots. It however wasn't all that complicated and there wasn't much of a risk that it would produce a strong solar flare. That changed however during the past 12 hours or so. Keep on reading to find out what sparked our sudden interest in this sunspot region.
What sparked our interest are a couple of C-class solar flares from this sunspot region. A closer look reveals that this sunspot region has been developing nicely during the past 12 hours with some rapid flux emergence in the middle of the group between the large trailer and leading sunspots. There is some magnetic mixing going on there and a small delta structure is forming. The chances aren't high yet but if this development continues we might see a low-level M-class (R1) event in the near future.
