The Artemis II mission, planned to send four astronauts to orbit the Moon, is facing potential delays due to heightened solar activity. A significant solar flare originating from sunspot region AR 4405 caused a high-frequency radio blackout in Southeast Asia and northern Australia. Following the flare, a Coronal Mass Ejection (CME) prompted the NOAA Space Weather Prediction Center to issue a G2 (moderate) geomagnetic storm watch. These solar events pose risks to the mission's electronic systems and radio communications.
