STATION FOR VISUAL OBSERVATIONS OF ARTIFICIAL SATELLITES OF THE EARTH IN HANOI (VIETNAM),

Abstract

The situation was set up in Hanoi in January 1959 under the administration of the Central Meteorological Service of Vietnam. Observations are made through an AT-1 telescope. Directing agency is the Geophysical Bureau of the Central Meteorological Service. The station maintains constant communication with the Soviet Ephemeral Center 'Kosmos' and with the Chinese observatory 'Purple Mountain,' from which ephemeral telegrams are received for Soviet satellites. These are then used in plotting the course of the satellites. The telescope is set up near a selected star. Configuration by means of two guides perpendicular to the path of the satellite. The satellite will be in the field of view for about 10 minutes and the course through the star group is plotted. (Author)
