Lyman alpha measurements of the Venus exosphere made by the Mariner-5 ultraviolet photometer on Oct. 19, 1967 are analyzed. The radiative-transfer exospheric model deduced from this analysis is highly asymmetrical with the exospheric temperature varying from 275 K on the day side to 150 K on the night side. The exobase density is 2 x 10 to 5/cu cm on the day side and at the terminator and probably increases toward the dark limb. A hot component was observed in the exosphere which is characterized by models with exospheric temperatures of 1000 K, 1500 K and 1130 K respectively. The column densities calculated from these hot models indicate an increase in abundance from bright limb to dark limb, and then a decrease downwind of Venus.
