NASA’S PUNCH SHARPENS SOLAR STORM FORECASTING IN FIRST TEST

NASA scientists announced that the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission successfully predicted the arrival of a solar eruption at Earth within a 30‑minute margin of error. The proof‑of‑concept test used continuous imagery from PUNCH to track the eruption’s trajectory, delivering the forecast ahead of the event.

The demonstration was presented on Tuesday at the Committee on Space Research (COSPAR) Scientific Meeting. According to NASA, the preliminary results are currently under review by the journal Space Weather. The test marks a first for PUNCH, showing the instrument’s potential for real‑time space‑weather forecasting.

Accurate forecasting of solar eruptions is critical for protecting satellites, power grids, and communications infrastructure from geomagnetic storms.

• PUNCH used continuous imagery to forecast a solar eruption’s arrival within 30 minutes.
• Results were presented at COSPAR and are under review by Space Weather.
• The test demonstrates the mission’s potential for real‑time space‑weather forecasting.
