Source region, magnetogram, and low coronal signatures of a CME that occurred on 3 April 2010. Panel a: Source of the eruption (AR 11059) as seen by SOHO/EIT 195 Å just before the eruption. Panel b: Zoomed-in region indicated by the red rectangle in panel a, showing post flare loops observed by SOHO/EIT 195 Å. Panel c: Same zoomed-in region showing the SOHO/MDI magnetogram. Red lines show tilt estimation.
