Summary: A solar wind disturbance buffeted Earth's magnetosphere on Sept. 23rd and triggered a day-long G1-category geomagnetic storm. High-latitude observers in Europe spotted some spectacular Northern Lights during the storm! The solar wind disturbance was the leading edge of a coronal mass ejection that left the Sun on Sept. 20th.
