A LASCO white-light coronagraph image from 2017 Apr 01 at 22:12 UT, with an off-pointed SWAP EUV (17.4 pass-band) image overlaid in the centre (from 22:07 UT). The signature of an eruption can be seen extending out to beyond 1 solar radii above the solar limb in EUV observations (indicated by a blue arrow), and the corresponding CME signature can be seen in the LASCO white-light observation above it.
