Photometry

Poorly known near Earth asteroids have the priority in photometric observations. In this manner the observations and results are continuously consulted with observatory AV ČR in Ondřejov.

The list of known Minor Planet Lightcurve Parameters is here.

The list of all Modra photometric asteroid campaigns is here.
