The sun unleashed a powerful X1.4 solar flare on March 30, causing a radio blackout on Earth and potentially raising concerns for NASA's Artemis 2 mission. The flare peaked at 11:19 p.m. EDT (0319 GMT) and caused widespread degradation of high-frequency (HF) radio signals across southeast Asia and Australia. The eruption came from active region 4405, a sunspot group that is now rotating further into Earth's view. NASA is preparing to launch Artemis 2, its first astronaut mission to the moon since 1972, on April 1. The heightened solar activity could complicate preparations if conditions worsen.
