A recommendation to the Union concerning the construction of certain tables was accepted.
A discussion was opened on the subject of collaboration in the study of open clusters. An application to the General Assembly was passed for a recommendation as follows: “That the Union call attention to the important problems connected with the open clusters and determinations of proper motions, radial velocities, magnitudes and spectra along the lines already inaugurated at several observatories.”
It was agreed that Dr Mineur should approach the observatories of the Carte du Ciel on the subject of photographing the open clusters for the future determinations of proper motions.
