Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4
 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequat
e for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will b
e posted immediately after reliable elements become available for new amateur satellites. More information may be found at http
s://www.amsat.org/keplerian-elements-resources/.

The following satellites have been removed from this weekâ€Ös AMSAT-NA TLE distribution:

*   Clark sat-1 NORAD Cat ID 58613 Decayed from orbit on or about 16 April 2024
  *   AISTechSat 3 NORAD Cat ID 44103 Decayed from orbit on or about 18 April 2024

[ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager, for the above information
