Use Big Dipper to find North Star By Larry Sessions in Tonight  Find-polaris-the-north-star

The Big Dipper swings full circle – 360 degrees – around Polaris in about 23 hours and 56 minutes. In 24 hours, the Big Dipper actually swings more than full circle, or 361 degrees. Does that make a difference? Yes! It means that – if you look at the same time each evening – the Big Dipper will appear just a little bit lower in the northwestern evening sky.

Compasses point to magnetic north not due north here is a map that helps you set your declination for your region.

People need to remind themselves that a compass can be effected by the earth beneath your feet Iron ore or composition as well as man made electric or electronic aberrations, so just be aware.

well things change it appears that the north pole is shifting I think we may need another declination charts soon.

The movement of the north magnetic pole has been the object of study since 1831. Initially, it was tracked moving into the Arctic Ocean at a rate of about 15km each year. But, since the mid 1990s, it has picked up speed. It’s now shifting at a rate of about 55km a year.
