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:

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,
