7693 20260105143609.0 POSTER-2026-0011 Gao, Yuhang Solar Orbiter/EUI observation of nanojets during a flare with unprecedented high speeds 2025 2025-04-30 Nanojets are small-scale jets generated by component reconnection, characterized by their motion perpendicular to the reconnecting magnetic field lines. As an indicator of nanoflare events, they are believed to play a significant role in coronal heating. Using high-resolution EUV imaging observations from the Solar Orbiter/Extreme Ultraviolet Imager (EUI), we identified 27 nanojets during an M7.6 flare on September 30, 2024. Most nanojets exhibit velocities around 1000 km/s, comparable to the typical coronal Alfvén speed. To our knowledge, these speeds are the highest ever reported for small-scale jets. The average kinetic energy of the nanojets is estimated to be 2.3×1025 erg, with events of higher speeds typically displaying greater kinetic energy and longer durations.
