Shock Location and CME 3-D Reconstruction of a Solar Type II Radio Burst with LOFAR

Type II radio bursts are evidence of shocks in the solar atmosphere and inner heliosphereemitting radio wavesranging 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 decametrewavelengths (20-90 MHz) is now possible with the Low Frequency Array ( LOFAR), opening a new radio windowto study coronalshocks which leave the inner solar corona and enter the interplanetary mediumand to understand their association with CMEs.
