Sunspot region 2699 has been transiting the earth-facing solar disk the past few days but was relatively quiet. However, today just past midnight, this sunspot region started to erupt with a long duration C-class solar flare. The solar flare started at 00:15 UTC and peaked at 01:35 UTC with a maximum measured X-ray flux of C1.5. Not a mighty impressive value but the long duration gave away that this event might have been eruptive...
