Hi Vince,

I'm not a command station but I think you mixed up Sun angle with ALON.
Stacey posted a table of attitudes and Sun Angles awhile back which is
available on amsat-dl.

Here's the current part of the table.

     AO-40  ATTITUDE - PRECESSION BEHAVIOR / W4SM
       Mystery Effect = -11.800 degs ALON/week
        DATE            ALON   ALAT    SA     ILL%
---------------------------------------------------
  2004  Apr  16 [Fri]  202.0   -1.0   -4.6    99.7
  2004  Apr  18 [Sun]  198.3   -1.0    0.6   100.0
  2004  Apr  20 [Tue]  194.6   -0.9    5.9    99.5
  2004  Apr  22 [Thu]  190.9   -0.9   11.1    98.1
  2004  Apr  24 [Sat]  187.2   -0.9   16.4    96.0
  2004  Apr  26 [Mon]  183.5   -0.9   21.6    93.0

As you can see although the sun angles are almost ideal, the ALON is
approaching 180 which puts the
antennas facing Earth at perigee.  For my QTH that makes for some mighty
high squints almost all the time.
