Abstract

The results of the IPHIR experiment on the USSR planetary mission to Phobos presented here are from data gathered during 160 days of the cruise phase of PHOBOS II to Mars, launched on 12 July 1988. The long uninterrupted observation produces a spectrum of the solar p-mode oscillations in the 5-minute range with a very high signal-to-noise ratio. Frequency and line shape determination is limited by the lifetime of the modes and the ‘noise’ from stochastic excitation. The temporal variation of the amplitudes of l = 0... 2 is discussed.
