Re: AO-7 eclipse plotting



Ingo,

Nova has a utility. It is in the menu system:

Utilities > Eclipse

You bring it up, choose the satellite and go for number of days and it will
show you all the eclipse periods. I'm using 2.1s version and it works quite
nicely. I print out the eclipses for 5 days at a time. Be sure to do the
"configuration" for the Eclipse utility where you choose the bird and the
number of days. Very handy.

LogSat Pro 5.2  shows the Eclipse in real time. It's on the right hand
column next to the map display. It shows three states:

Eclipse Away (in sun)
Eclipse Toward (in sun)
Eclipse Eclipse (in darkness)
