Overview
- Instruments detected rising solar-wind speed and density as Earth moved into a high‑speed stream from a large, equatorward coronal hole.
- The Laboratory of Solar Astronomy at IKI RAN reported the onset of the third geomagnetic disturbance of October.
- Specialists assess the influence as moderate to weak, with a strong geomagnetic response considered unlikely and a weak storm the most probable outcome.
- Several M‑class flares were recorded overnight, but researchers say they pose no risk to Earth's magnetosphere and are not driving current conditions.
- Scientists expect the coronal‑hole stream to dominate space weather for about 48 hours, with stabilization by midday October 20 and roughly a week of quiet to follow.
