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/. This week there are no additions or deletions to the AMSAT TLE distribution. *[ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager for the above information]*
