A powerful geomagnetic storm caused auroras in Yellowstone

In the evening, the Earth caught the coronal mass ejection that occurred on the Sun on May 23rd. Until 23:45 Moscow time (May 27), the storm was weak, but with the dawning of the European part of Russia, the storm is the Sun of the G3 level. From 5:00 to 7:00 Moscow time, the Q-index reached values of 8-9. If it had occurred a few hours earlier, then the polar lights could be seen in the latitude of the Caucasus!
