摘要

Type II radio bursts are evidence of shocks in the solar atmosphere and inner heliosphere emitting radio waves ranging from sub-meter to kilometre lengths. These shocks may be associated with coronal mass ejections (CMEs) reaching speeds higher than the local magneto-sonic speed. Radio imaging of decametre wavelengths (20-90 MHz) is now possible with the Low Frequency Array (LOFAR), opening a new radio window to study coronal shocks which leave the inner solar corona and enter the interplanetary medium and to understand their association with CMEs.
