NASA's PUNCH sharpens solar storm forecasting in first test

Using continuous imagery from NASA's PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, scientists predicted the near-Earth arrival of a solar eruption to within 30 minutes in an initial proof-of-concept test. The results, presented Tuesday at the Committee on Space Research Scientific Meeting and under review at the journal Space Weather, could revolutionize the way Earth-impacting storms are forecast.
