Site Codes

The COSPAR site code is a unique number for identifying observing sites for satellite trackers. COSPAR site codes are assigned to satellite trackers by folks at the Visual Satellite Observers Group in cooperation with COSPAR The two sites commonly listed in my satellite reductions are my home (8336 = TULSA1) and the Astronomy Club of Tulsa Observatory (8335 = TULSA2).

These are not the same as the COSPAR International Designator for satellites which are for objects launched to space.

MPC (Minor Planet Center) site codes are also assigned, but for minor planet tracking. Site 323 is the remote scope I use in Perth. A list of all the MPC codes is at
