Sun, 03 Sep 2017 - Large Sunspot Group Takes Centre-stage

Active Region (AR) 2674 has steadily developed since it appeared over the solar eastern limb in late August. A couple of days ago, I thought it was just visible to the protected naked eye so worth watching to see if it remains that way, becomes easier to see or starts to fade away.

AR2674 is currently type Fhc and lies north of the solar equator at +14 degrees latitude. It is also thought to be solar flare active too. All this is somewhat unexpected at this part of the Sunspot Cycle.

Thank you to Carl Bowron for the above image taken on September 1st.
