The flare seen here took place at 11:54 CET on Saturday 3 April and recorded by ESA's Proba-2. Significantly, this eruption was lined up with Earth as it erupted, sending a vast number of charged particles hurtling towards us, reaching Earth the following Monday, 5 April. Observing in extreme ultraviolet, Proba-2 acquired an image of the event every 100 seconds.
