Time history of the metre-wave radio emission during the late type III and type II bursts: a) 1D images projected onto the solar east-west direction at 150 MHz (y-axis graded in solar radii from the eastern to the western limb) showing a continuum emission and a sporadic source on its eastern side at around 14:07 UT, b) dynamic spectrum between 70 and 20 MHz and c) time-difference spectrum of b). The dashed lines are fits of the upper and lower borders of the type II burst in b).
