sun angle & illumination factor



Hello all

For better understanding what W4SM has explained Manfred Maday, DC9ZP
has prepared a list which shows the relation between sun angle and
illumination factor for the time till end of april for ALON/ALAT 0/0.
The list is shortened by showing only every third day.

If the illumination factor becomes lower than 80% you may expect 
corrections of the ALAT/ALON which results in a worse squint angle. 

If you have any questions you may contact Manfred at dc9zp@amsat.org.
