Abstract: On the 1st and 3rd April 2017 two large solar eruptions, which were associated with an M4.4 and M5.8 class flare, respectively, were observed on the solar western limb with the PROBA2/SWAP telescope. The large field of view of SWAP combined with the exceptional circumstances of the satellite being off-pointed in a favorable position to view the events, provide us with the rare opportunity to study these eruptions up to approximately 2 solar radii, where space-based coronagraph observations begin. SWAP observations reveal off-limb erupting features as well as on disk EUV waves initiated by these eruptions. Using this unique set of observations, the evolution of these two events is tracked and the propagating speeds of both the eruptions and the on-disk EUV waves are calculated.
