Overview
- The Proba‑3 animation, published this week, documents three distinct prominence eruptions captured on September 21, 2025 within five hours.
- Using two satellites flying 144 meters apart with millimeter precision, the mission creates artificial eclipses that continuously reveal the faint inner corona.
- ASPIICS images the region from roughly 1.1 to 3 solar radii, filling a long‑standing observational gap between EUV imagers and traditional coronagraphs.
- The released sequence blends Proba‑3’s visible‑light views, including helium D3 line data, with NASA SDO/AIA imagery that renders the solar disc.
- Scientists describe the dataset as valuable for probing coronal heating and mass‑ejection processes, with potential to improve space‑weather forecasting as analysis continues.
