Measurement and Uncertainty. In the Parallax lab, you were asked to estimate the uncertainty in your results, from your guesses about the sources of error in the measurement. This lab explores, in a little more detail, how one can express the level of confidence associated with a scientific measurement.
Sunrise: 07:08AM. Sunset: 08:05PM. Day length: 12h 57m. Solar noon: 01:37PM. The current local time in Florida is 97 minutes ahead of apparent solar time.
The exact dates vary, but the sequence is always the same: earliest sunset in early December, shortest day on the solstice around December 22, latest sunrise in early January. And so the cycle continues. Bottom line: In 2015, the December solstice comes on December 21 at 10:48 p.m. CST. Thatâs December 22 at 4:48 UT.
