    Re: Searching for Air Almanac 2025

    Just a thought.  Does anyone still have ‘aira20’ and ‘aira24’ amongst their downloads.  I bet you do Gary.  Please check a couple of daily pages against each other.  I seem to remember someone telling me once that the values of GHA Sun and Aries should be within one minute of arc of the values from four years earlier.  If so, you could, at a push, use ‘aira21’ in place of ‘aira25’ until 'aira25' becomes available. 
    Further to that.  I just checked for 1 Jan and 1Jul via various sources; the Sun will be almost spot on.  For Aries, it might be wise to add in a couple of extra minutes of arc.  DaveP
