The End of Aurora: Day 133


Long cold winter nights, crisp and clear from an absence of moisture and deafeningly silent, have been replaced by the cloudy restless nights of spring. With a rapidly shrinking window of darkness as the sun prolongs its attendance in the sky, by the end of April alone, the time between civil twilight will span a mere four hours. The aurora season is coming to an end. The solar wind will continue to blow, periodically sparking geomagnetic storms throughout the summer months, but the sun and clouds will make most viewing opportunities impossible. A small price to pay for the reappearance of sunshine.
