Hi, I just loaded the full satellite catalog file from Space-Track and it shows 11669 objects, a number that I've never seen really drop. The youngest elset was 0.5 day old and the oldest was at 30.3. The description on Space-Track says : These files are generated twice a day, every day and consist of the most recent elset for every object in the specified group that has received an update within the past 30 days. So there is more objects up there, but I guess the great majority of them (those that have been catalogued) are in the elset file. High altitude objects look difficult to track...

An analyst I respect a lot has told me that the number of cataloged TLEs posted by space-track has decreased by 40% since November (since roughly when those six satellites, including the CLUSTER II satellites, were lost). I'm only able to check a few satellites at a time and was wondering if anyone had also noticed this? Thanks! ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
