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