I had mentioned this when I met you in Huntsville but wanted to get it on the list – The 5 digit satellite catalog numbers have expired. Today, satellites are assigned 6 digit numbers. Classic TLE data will not be provided for new satellites with 6 digit IDs. Orbital data is provided for these new satellites in OMM data formats or in a transitional Alpha5 format. Your AMSAT Tracks overlay will need to consume these new formats to track any new satellites going forward.
