    I posted this on September 10th:

    "You can get the current edition of HO 249 at Celestaire, the same place I had recommended to you as a source for a bubble sextant. Ken Gebhart operates Celestaire and he also posts on this forum."

    That included the long term almanac. But, I tried the link today and it didn't work. You can buy the 2015 Volume 1 of HO 249, including the almanac at:

    Subject: [NavList] GHA Aries long term Table?


    2015 is coming....surely.

    HO 249 Volume 1 page 340 has "Table 4- GHA Y for the years 2006 to 2014" which is a very compact way to determining GHA Y (Aries) for stars.

    See here (page 339)-

    I use it instead of carrying around the NA. (I can easily calculate Hc and Az using the Spherical Trig formulas so I can reduce the amount of paper on board).

    But, that sheet will expire this year. Do you know of the same Table 4 for the coming years?

    Or rather....do you know of quick, accurate way to determine GHA Aries?

    Thanks,
     
    Sam L.
