    LAN at higher lattitudes
    From: Murray Campbell
    Date: 2004 Jan 8, 12:35 -0800

     I though i would begin by learning the noon shot, but
    i am at 52 north and the sun is so low and flat right
    now and i'm just learning to use the sextant....i will
    try to take the sites way before and after noon and
    average them as George mentioned in the recent LAN
    discussions.
    
     My beginner question is what the practical limits are
    for measuring altitudes accurately at high lattitudes?
    If the sun is above the horizon is it always useable
    or is it best (and more accurate) to switch to a body
    higher in the northern sky?
