[amsat-bb] alon of AO40

[Estes Wayne-W10191 <W10191@xxxxxxxxxxxx>]

Is the AO40 alon increasing 1 degree per day, as stated on the AMSAT-DL web site?

Or is it increasing 0.7 to 0.8 degree per day, as predicted by Peter Guelzow on 29 December:

  Date         Alon  Alat
  -----------------------
  2002 Jan 08   300  -10
  2002 Jan 15   300   -5
  2002 Jan 22   300    0
  2002 Feb 19   320    0
  2002 Mar 19   340    0
  2002 Apr 13   360    0
  -----------------------

My main concern is to know what the squint angle will be for a hamfest AO40 demonstration on 24 March.  Using the "1 degree per day prediction", the alon would be 356 on 24 March, giving good squint angles for the hamfest.  Using Peter's prediction the alon would be 344 on March 24, giving marginal squint angles for the hamfest.
