Aurora and recurrent geomagnetic storm

Geomagnetic activity associated with long-lasting coronal hole on the Sun (see, our previous post at https://gongnisp.blogspot.com/2025/09/recurrent-geomagnetic-storms.html) seem to continue. Last night (7 November 2025), a moderate geomagnetic storm hit the Earth and produced some beautiful aurora. The geomagnetic activity associated with this long-lasting coronal hole is approximately marked by black ovals. Geomagnetic storm on previous night (also included to the last oval) is related to solar flare activity.
