Weak Geomagnetic Ripples Detected as Coronal-Hole Stream Nears Earth
Forecast points to a modest solar-wind arrival around October 12 with a possible delay into Monday.
Overview
- Russia’s Space Research Institute solar lab reports minor geomagnetic disturbances on Saturday.
- No geomagnetic storm is under way, and the lab expects the fluctuations to subside within hours.
- Scientists link the activity to a compressed, denser region preceding a high‑speed stream from a coronal hole.
- The primary flow has not reached Earth yet and could arrive later than earlier projections, potentially Monday morning.
- Other solar indicators are quiet, making the incoming coronal‑hole stream the main space‑weather focus for the next couple of days.
