THE ANOMALOUS COMPONENT OF COSMIC-RAYS - OXYGEN LATITUDINAL GRADIENT

We have studied the latitudinal evolution of the anomalous cosmic ray oxygen component at ULYSSES during its journey to the south pole of th e sun. Observations from the COSPIN Low Energy Telescope at ULYSSES ar e compared with observations in the vicinity of the Earth, provided by the HILT sensor on the SAMPLEX spacecraft. We present results in two oxygen energy ranges from 8 to 12 MeV/n and from 12 to 16 MeV/n over a period from August 1992 until end of May 1994. Only quiet time period s which contain no solar energetic particles are taken into account. T he data set covers a latitudinal range of about 50-degrees and show fo r both energy channels a decrease of the SAMPLEX to ULYSSES flux ratio equivalent to a positive latitudinal gradient of approximately 2%/deg ree.
