"Historic Sunspot Returns, Threatening Blackouts and Auroras"
TL;DR Summary
The sunspot AR3664, responsible for the strongest magnetic storm in two decades, is returning and could cause blackouts and auroras. A recent class X2.8 solar flare and coronal mass ejection from this sunspot have raised concerns, although the CME won't impact Earth. The sunspot will be fully Earth-facing around June 6, potentially generating another powerful solar storm.
