Visibility IV / V
At midnight it started to happen. The belt of northern lights passing through the zenith from east to west would go into the southern sky, return to the zenith, and quickly begin to brighten from the east. In an instant, the narrow belt spread like a crown almost the size of the sky. The center of Corona was near the Moon and the bright green rays spread in every direction. The shutter speed of the camera had to be reduced to half a second to stop the movement. Even the bare eyes bright green and dimmer red light. What a great storm!
