CATALOG OF SOLAR-TYPE-II RADIO-BURSTS OBSERVED FROM SEPTEMBER 1990 TODECEMBER 1993 AND THEIR STATISTICAL-ANALYSIS

Solar type II radio bursts represent the radio signature of shock wave s travelling through the solar corona. They are associated with flares , coronal mass ejections (CME's) and interplanetary shocks. Type II ra dio bursts appear as emission stripes slowly drifting from high to low frequencies in dynamic radio spectra. The spectral features of all so lar type II radio bursts observed by the new radiospectrograph of the Astrophysikalisches Institut Potsdam in Tremsdorf during the time peri od from September 1, 1990 to December 31, 1993, i.e., during the first part of the ULYSSES spacecraft mission, are summarized and statistica lly investigated.
