Overview

• IKI RAN says the geomagnetic situation on Friday is expected to remain calm.
• Over the past day, conditions stayed quiet as solar flare activity was slightly elevated without posing risks to Earth.
• Earth fully moved out of the coronal‑hole–driven disturbed plasma flow by late Thursday, with solar‑wind speed, temperature and density returning to average levels.
• The strongest disturbance peaked on September 15 with events up to G3, after which indices stabilized and no new events were recorded from September 16 to 18.
• Scientists note only weak plasma ejections that mostly miss Earth and say monitoring and daily forecasts continue.
