Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/ https://www.amsat.org/keplerian-elements-resources/. The following satellite has been added to this week's AMSAT TLE distribution: CSS (TIANHE-1) NORAD Cat ID: 48274 Chinese space station, possible ham gear aboard We recognize that the entire space station is referred to as "Tiangong", but use the same identifier as the US Space Force for consistency with other sources of orbital information. *[ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager, for the above information]*
