Find the tilt of earth from time of sunrise?

Start here: http://www.usno.navy.mil/USNO/astronomical-applications/data-services/rs-one-day-us Then go here: http://www.usno.navy.mil/USNO/astronomical-applications/data-services/alt-az-us If and when you figure out what those two sites are telling you, you will have all the information you need to answer the question.

Interesting question... If you are at the equator, it doesn't make a difference. If you are at some point between the pole and the equator, the time of sunrise will change between summer and winter, this is why the days get longer and shorter. So you need to know your latitude. Give me a few minutes, I'll edit this with a full explaination when I've worked it out... You know what? as its one in the morning here, I'm gonna leave you hanging for a few hours. meeting a mathematician buddy tomorrow, so will get back to you at some point.
