Earth may experience stormy space weather due to the reappearing massive sunspot cluster AR3697, known for powerful solar flares.

A giant sunspot cluster similar to the one causing the 1859 Carrington Event may trigger a cannibal coronal mass ejection but is unlikely to cause major problems.

A massive solar flare from sunspot cluster AR3664, the largest of the current cycle, occurred on May 14.
