    Re: Calculate GHA Aries in your head

    A good reson to limit the list of stars that beginning navigators have to learn is that many are intimidated by all the zillions of stars overhead. William F. buckley, a noted sailer, writer and navigator, admitted that  he could never learn all the stars so he stuck to sun lines. I chose a list of ten stars to memorize which are well arraded so that some of them are always visible almost anywhere on earth. Have you students learn just this short list and they will be good to go,  I checked my selection of stars by use of the 2102-D and in the northern hemisphere there are never fewer than three stars above the horizon and usually 5 to 7. In the southern hemisphere, south of 55 south, there are occasions when only 2 stars are above the horizon, but usually more even that far south. North of 55 south there are at least 3 stars up and usually more,
