Bulletin
Solar activity is very low, no changes are foreseen for the next 48h. Geomagnetic conditions have been quiet to unsettled (due to a sector boundary crossing on September 10). The fast solar wind from a coronal hole may arrive to the Earth in the coming 48h, causing active geomagnetic conditions with possible minor storm levels.
