Today, September 23rd the sun crosses the equator passing south an event known as the autumnol equinox. I was really excited to see this picture as I was aware that this event was takign place today! It crossed at approximatley 3:09 Universal Time. With the sun on the celestial equator, we will experiance 12 hours of daylight and darkness. Days in the northern hemisphere will continue to grow shorter as winter approaches and the sun decends lower in the sky. This picture is really awesome to look at - you can see loops and arc that trace the glowing plasma!
