Time series of STEREO-A 195 Å (a–c), 304 Å (g), and STEREO-B 195 Å (d–f) running difference images illustrating the eruptions of flux ropes R1 and R2. Composites of STEREO EUVI 195 Å and COR1 white-light running difference images (h), and SDO/AIA 94 Å and SOHO/LASCO C2 running difference images (i), displaying the relationship between flux rope eruptions and a CME. R in i) denotes flux ropes, and D in c) and h) a dark region. The red and blue curves in b) describe R1 and R2, and the green arrows the expanded flux loops. The colored triangles and diamonds in c) and f) separately represent three positions of R1 and R2. The FOV of d)–f), h) and i) are 1.0 R_⊙ × 1.0  R_⊙, 2.7 R_⊙ × 2.7  R_⊙ and 6.2 R_⊙ × 6.2  R_⊙. The green window in h) denotes the FOV of a)–c) and g), 1.0 R_⊙ × 1.0  R_⊙.
