The storm reached a moderate G2 level on the NOAA five-point scale, where G5 represents an extreme storm. Geomagnetic activity has now stabilized, and the likelihood of new strong disturbances is assessed as low.
The storm was caused by a stream of fast solar wind from a medium-sized coronal hole. The peak activity occurred in the morning, after which the indicators returned to normal. The first storm of this autumn took place on September 8 and was weaker, at the G1 level.
