MPC observations statistics

ITF - Observations of tracklets (1-night objects)

Sorted by number of observed objects

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 04-16-2024
