\u00a027 January:<\/strong> Onset of a first CME (CME1) at 09:54 UT ((POS 289 W 45 V= 273 , 361, 690 Km\/s)\u00a0 followed, in the same region,\u00a0 by a second faster one (CMEH01) at\u00a0 12:30 UT<\/strong> (1136, 1000, 1068 km\/s) and located on the lowest part of CME1 (no image between (12:06-12:30 UT). This encounter marks the onset of the CMH01\/CME1 and then CMEH01\/ambient medium interactions.\u00a0 #12:32 UT<\/strong>: a type II burst is detected by the Nan\u00e7ay DAM spectrograph then by WIND\/Waves.\u00a0 12:33-12:39 UT<\/strong>: a weak radio source, observed by the NRH at 164 MHz, is rising roughly from 1.4 to 1.8 Rs\u00a0 (V ~ 260 Km\/s);\u00a0 the C2 12:30 panel, upon which the NRH image at 12:33: 47 UT has been superposed, shows that this source is located\u00a0 below CMH01 . 12:35-17:00 UT<\/strong>: During this whole period, the Wind\/Waves radio spectrograph displays a multiple-component emission of long duration (14000-300 kHz) . 13:31 UT:<\/strong> CME2 has overtaken CME1 and shows a\u00a0 broad extension in latitude which continues to increase as observed by C3 until 23:42 UT.<\/p>\n

This event shares the following characteristics<\/em>:\u00a0 Continuum long duration (B)<\/strong>,\u00a0 Interactions between at least two CMEs and with the ambient medium , Type II burst.<\/strong><\/p>\n

28 January: 11:10 <\/strong>Onset of CMEN02 January 28: 10:54 UT (PA 143 (deg), Width 62 (deg), V 524, 738, 965 Km\/s).\u00a0<\/strong> 11:10-14:00 UT:<\/strong> Onset of a continum (B),<\/strong> detected at 164 MHz( see the red arrow) and 11:10-14:27 UT <\/strong>of a bursty\u00a0 activity ; both emissions are located in the south hemisphere. The source of the continuum is the eastern one. The bursty source is located in the region of open field lines and might\u00a0 originate from the interaction between the CME estern edge,\u00a0 which becomes bright, and the open field line. Note that, to take into account the origin of the source observed at\u00a0 14:27:11 UT, a similar effect\u00a0 between the open field and the broad region which was the seat of CMEH01 on January 27 and tracked \u00a0 by C3 until at least 23:42 UT,\u00a0 cannot be excluded.<\/p>\n

 <\/p>\n

Note in conclusion that, taking into account the propagation aspects of the 27 and 28 events, the second one was considered, in the Bocchialini et al.\u00a0 submitted publication, as more favorable than the first one.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
