Oui Alain, je suis un ingenieur, mais un ingenieur chemie qui parle un peu Francais. To find south, use the sun at noon. Determine the exact time of local noon, corrected for time zone, longitude, and equation of time. Today at your location solar noon is 12:00 MET + ((15-7)/15x60) + 0:11 = 12:43. I use the Dialists Companion Program available from NASS to determine these corrections. Mark the shadow of a plumb line at that exact time. This gives you an accurate north south axis. This old fashion method is better for finding south than a modern GPS. Roger Bailey
