RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Solstice Trivia

Since you're along for the ride anyway, here are a few tidbits about your vehicle on these first days of summer. Earth's axis is currently tilted at an angle of 23.44° relative to its orbital plane, and represents the maximum northward or southward track where the sun can be directly overhead (zenith) at noon. The Tropic of Cancer and Tropic of Capricorn are located at 23.44° of latitude accordingly. The northern summer solstice (from Latin terms meaning "the sun standing still") occurs when the sun reaches the Tropic of Cancer, and the winter solstice occurs at the Tropic of Capricorn. Due to minor gravitational tugs by neighboring planets, the tilt angle varies between 22.0° and 24.5°, and is currently decreasing by 0.47 second of arc per year. The entire precession period occurs in about 25,700 years.
