Latitude Chart for Major Cities of the World

To aid in the polar alignment procedure (

see page 57

), latitudes

of major cities around the world are listed below. To determine

the latitude of an observing site not listed on the chart, locate the

city closest to your site. Then follow the procedure below:

Northern hemisphere observers (N): If the site is over 70 miles

(110 km) North of the listed city, add one degree for every 70

miles. If the site is over 70 miles South of the listed city, subtract

one degree per 70 miles.

Southern Hemisphere observers (S): If the site is over 70 miles

(110 km) North of the listed city, subtract one degree for every 70

miles. If the site is over 70 miles South of the listed city, add one

degree per 70 miles.
