Measure the azimuth of a bright near-equatorial star at, say, 15 degrees altitude in the east, and again 15 degrees altitude in the west. (Mark these out on the ground, using local landmarks, not with a compass.) Split the difference to get a north-south line. You might have to do the two measurements at different times of the year. Do the same with the sun, around a solstice, or else applying some correction for its changing declination. --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
