Sunspot Group AR2671

A remarkably-long sunspot group is sprawling across the solar disk. AR2671 stretches 140,000 miles from end to end, almost twice as wide as the planet Jupiter.

I imaged it today from Roberts Creek – I didn’t want to miss such an impressive group in  a period of solar minimum!

Tomorrow we have the partial eclipse here on the coast and this sunspot group should still be visible as the moon moves across the solar disc. Check it out.
