The horizontal solid lines mark the time interval when the CMEs are visible in the field of view of LASCO C2. The onset time of the eruption of filaments F1 and F2, as well as that of the X1.2 X-ray flare are indicated by F1, F2, and X respectively. No on-disk activity associated with CME3 was detected.

The EIT 195 Å images ( upper two rows) show the eruptive process of filament F1 (indicated by arrow F1) in the lower corona. The WICE technique was used to enhance fine structures of filaments and flare ribbons. When the filament F1 reached certain height, flare-ribbons appeared at the two sides of the place where F1 used to sit (indicated by the arrow R1). They later connected themselves by loops (indicated by the arrow L1). The LASCO C2 and C3 white light images ( lower two rows) show the development of CME1 between 2 and 30 $R_{\odot }$ . The leading edge of CME1 is pointed out with the arrow E, while the core is indicated by the arrow C.

The solid line indicates the fitting result to the F1 height-time data according to Eq. (1), the dashed line indicates the quadratic fitting based on Eq. (1) to the CME1 height-time data for a₃=0. The time of t=0 for fittings is 00:00 UT.

The EIT 195 Å images ( two upper rows) show the eruption of filament F2 (indicated by the arrow F2) in the lower corona. Two flare ribbons (indicated by the arrow R2) and a group of post-flare loops (indicated by the arrow L2) appeared near the location where the F2 sat. The LASCO C2 and C3 running difference images ( two lower rows) show how CME2 (arrow marked CME2) expanded and interacted with the core of CME1 (arrow marked F1) and the leading edge of CME1 (arrow marked CME1).

The solid (dashed) lines specify the quadratic fitting to the F2 (the leading edge of CME2) height-time data. The time t=0 corresponds to 00:12 UT.

The white arrows in a)- f) indicate the expanding part (leg) of the streamer, while the shape and profile of the other leg remained almost unchanged (white arrow in h)). The angular span of the CME-associated magnetic arcade is marked by two straight lines in the C3 frames.
