Pedro,
This is great, muchas gracias! One question, however - are the "past passes" historical values "locked in time", or are they "back calculated" from current keps?

Hello, Upon suggestions, a small calendar had been added over Date Label on http://amsat.org.ar/pass Hoping useful to allow retrieve past and future satellite passes. 73, lu7abf, Pedro
Hi Roy,
THANKS! for nice & rewarding comment on new calendar facility on http://amsat.org.ar/pass
The past & future passes where a date can be selected are calculated on the fly using as you wisely said from current keps. However if a much further/previous date (over three months) is selected calculation will have a minor difference with actual, given keps changes over time.
Have a good time and enjoy the birds.
