Just when you thought old sunspot AR3088 was dead, it’s back. The decaying sunspot is growing again, adding more than 50% to its area over the past 24 hours.

This is the sunspot’s second time around the sun. The first time in August it peppered Earth with dozens of solar flares, and later hammered Venus with one of the strongest farside radiation storms in decades. The sunspot reappeared on the Earthside of the sun a few days ago and was renumbered AR3102. It appeared to be in decay.

Not so fast? Stay tuned.
