URGENT: We ran out of 5-digit catalog numbers on 2026-07-11. The official USSF SATCAT is now at 101074. All newly cataloged objects have 6-digit catalog numbers of 100000+ and GP data will not be available for them using the TLE format. Please be sure to use one of CelesTrak's other formats which remove the 5-digit catalog number limitation (and finally fix the Y2K problem) and to adhere to our usage policy when retrieving any CelesTrak data. Follow @TSKelso on Bluesky for the latest updates, tutorials, and changes as we move forward. Spread the word! ‑ TS
