Projection of a composed image from SDO/AIA 193 Å, STEREO-A and STEREO-B EUVI 195 Å at the moment of the solar flare preceding the CME release. The axes correspond to latitude and longitude (in degrees) as seen from STEREO-A in the ecliptic plane. Purple ellipse shows the AR, while the red, blue, and green boxes indicate the surrounding CHs. Stars represent the projection of each location (green, Earth; red, STEREO-A; blue, STEREO-B). See text for more details.
