Scientists successfully predicted the near-Earth arrival of a coronal mass ejection to within 30 minutes in a proof-of-concept test using PUNCH spacecraft imagery.

Key Details

• Analyzed continuous 3D imagery of a coronal mass ejection that left the Sun on May 31, 2025.
• Computer model settled on a final prediction 12 hours after the ejection, predicting arrival 8 hours later.
• Achieved arrival time accuracy within 30 minutes, 10 times more accurate than current 5-hour window methods.
• Results presented at the Committee on Space Research Scientific Meeting and submitted to Space Weather.
