This event occurs in coincidence with the brightening of the trailing part of a CME which displays a slow evolution (<em><strong>CME1<\/strong><\/em> Partial Halo 00:30 UT, P 311, W <em>&gt;<\/em>173, V 363, 376, 280 km <sup>\u22121<\/sup>).<\/li>\n<li>12:02-12:10 UT: Type III burst followed by the onset of a type II burst detected by WIND\/Waves, 12:10-12:45 UT (4200-1300 kHz). The radio emissions result from the interaction between <em>CME1<\/em> and a faster CME2 (<strong>CMEN34<\/strong> 12:07 PA 13 Width <em>&gt;<\/em> V 562,512, 532 km s<sup>\u22121<\/sup>), see in particular lower raw, middle and right panels.<\/li>\n<\/ul>\n<p>Note that the observing coverage of the two CMEs is very poor, with no observation for two time periods (09:30-10:35 UT and 11:09 -12:07 UT). We suggest that both episodes could be associated with CMEN34 rising and interacting with and which has a smaller velocity. on July 31<\/p>\n<p>This event shares the following characteristics:\u00a0 <strong>Type IV (A-B) and a Type II, Encounter<\/strong> which\u00a0 might result\u00a0 from the <strong>interaction <\/strong> between CME1 and CME34.<\/p>\n<p>CME34 continues its progression with decreasing velocity.
