MPC observations statistics

SATOBS - Observations of natural satellites

Sorted by first year of observation

The statistics were made with a self-developed program by Jost Jahn, Amrum, Germany, itfstat@jostjahn.de.

They will be updated some days after publication of new files by the MPC, mostly each 2 months or so.
Date of this file is 06-23-2021
