I don't know of anyone who keeps up with every satellite, every day. It's a lot of work, if you have time, you could do it for us? But, in the meantime, lyngsat gets it's info from people like you who submits it to them, and I guess when it's verified (I guess a 2nd or 3rd time submitted), they post it. Some of that stuff stays forever, even when it's gone, because nobody bothers to let lyngsat know it's gone. Lyngsat happens to be in Europe, and can't see most of the sats we watch, so it's up to us to keep him informed.
But, in the meantime, you can also look at this, which is the best one on this side of the big pond: http://www.global-cm.net/
and it's more up to date. Look in the MPEG 2 Section, about half way down the page.
SatcoDX also has updates that you can use to cross reference against Lyngsat.
Once again I think they are prone to get out of date as well. There's a CD of the SatcoDX program that you can get with each issue of Tele-Satellite magazine with a subscription , but I don't know if that provide more current information than what's up on the web site (I assume it does).
