Winter Officially Starts this Week!
The (winter) Solstice (northern hemisphere) occurs on
December 21, 2004 at 12:42 UT (4:42 A.M. PST).
In the northern hemisphere the noon sun angle, as well as the length of daylight, has been decreasing since the September equinox (Sept. 22, 2004). On Sunday, December 19, a 12.0 inch ruler cast a 29.25 inch shadow.
This indicates a noon sun angle of 22 degrees above the horizon.
Compare this with the noon shadow on May 15, 2003 (click here).
