ULYSSES OBSERVATIONS OF A CORONAL ORIGIN PARTICLE EVENT AT 32-DEGREESSOUTH HELIOGRAPHIC LATITUDE

A remarkable streaming beam-like particle event of 60 keV-5 MeV ions a nd of 38-315 keV electrons has been reported previously. This event ha s been associated with the passage of a Coronal Mass Ejection (CME) ov er the Ulysses spacecraft on June 9-13, 1993. At this time, the spacec raft was located at 4.6 BU from the sun and at an heliolatitude of 32 degrees south. It was proposed (Armstrong et al., 1994) that the parti cle injection source could have been of coronal origin. In this study, we analyse the solar activity during this period. We identify a regio n of solar radio noise storms in the corona and in particular, a flare on June 7 that presents all the required characteristics to produce t he hot plasma beam observed in the interplanetary medium.
