Photometry of the United Kingdom Spacecraft ARIEL-4, Space Object 5675: Optical Properties of Spacecraft (OPOS) Application Report Number 4.

Abstract

Optical observations of the ARIEL-4 spacecraft, space object (S.O.) 5675 on 6 and 15 July 1972 indicate that the spacecraft is experiencing a somewhat greater unbalance than the preceding spacecraft in the series. This is evidenced by a 2.2 degree coning angle in its spin-stabilization, compared with 0.6 degree for ARIEL-3 (S.O. 2773). These values are obtained by measuring the amplitudes and times of specular glints produced by sunlight reflecting from solar cells mounted on the main body of spacecraft. (Author)
