An automated pipeline forecasts CME magnetic fields at L1 using initial magnetic obstacle data, achieving errors of roughly 5 hours in timing and 10 nT in strength comparable to full-event reconstructions.
Aspect ratio of fast and slow Earth-directed CMEs shows a systematic three-phase evolution from corona to 1 AU with reduced radial expansion efficiency at larger distances.
SKA's higher sensitivity and bandwidth will enable fuller exploitation of radio methods for measuring CME magnetic fields and improving space weather predictions.
