On the picture one can see a series of bright dots. These dots indicate a tumbling movement of the satellite. I measured their period as between 1.5 and 2 seconds. The field of view is about 15 x 12 arcminutes.
North is up, East is left.
Intelsat 4A-F6 was the 6th model of the 4A series. It was launched on 31 March 1978. It is 2.8 m long, has a diameter of 2.39 m and weighed 1500 kg, including the propellant for station-keeping. The dimensions do not include the solar arrays which span about 5 m on each side. When this photograph was taken, the satellite was at a distance of 37'150 km.
