Abstract
Measurements from the Ulysses COSPIN (Cosmic Ray and Solar Particle IN vestigations) High Energy Telescope between 80.2 degrees S solar latit ude and the sun's equator from September 1994 to March 1995 confirm th at the modulated fluxes of galactic cosmic rays and anomalous componen ts depend only weakly on heliographic latitude in the inner heliospher e at this phase of the salar cycle. The new observations were made ove r a radial range of only similar to 1 AU during a period of nearly con stant modulation and thus require less correction for radial and tempo ral variations in modulation than measurments made during Ulysses clim b to maximum latitude.
