Tomorrow (September 23, 2011) is the September equinox (also referred to as autumnal in the northern hemisphere)—the moment in time when the sun crosses the equator and heads southward along its path. At this moment, which officially occurs at 9:04 am Coordinated Universal Time (UTC), the Earth’s axis is perpendicular to the line connecting the centers of the earth and sun. On this day, it is possible to calculate one’s latitude by determining the angle of the shadow cast by the midday sun.

So, the equinox activity didn’t turn out quite as I would have expected, but it was fun to be outside on the top deck in the sun and the wind, so I’d say it was a success!
