Earth may experience another solar storm in early June as the hyperactive sunspot cluster rotates back into view.
It’s back! After unleashing the strongest geomagnetic storm in more than 20 years, the notorious sunspot cluster AR3664 is once again visible and still spewing copious amounts of radiation into space. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center recorded a solar flare erupting from the southeast limb of the Sun on Monday. Sunspot AR3664 is likely responsible for the flare, which was classified as a strong X2.8.
warned that the charged particles released from the Sun this week could reach Earth, although it may take a while to get here due to the location from which it erupted. The last time AR3664 was visible, it had grown to nearly 124,300 miles and was becoming one of the most active regions on the Sun during this current solar cycle. As the Sun rotates on its axis, the sunspot became hidden from our view for around two weeks but now it’s back.
