The following satellite has been removed from this week's AMSAT distribution: ENSO NORAD Cat ID 58470 Decayed from orbit on or about 09 November 2025 The following satellite has been added to this week's AMSAT distribution: CEVROSAT1 Provisional ID 98526 Note: Resource constraints at USSF 18SDS evidently are preventing generation of TLE for this satellite. The element set provided is unusally poor, expect the satellite to pass a minute or more away from predictions. Joe Fitzgerald KM1P AMSAT Orbital Elements ...Continue Reading
