PROBA2 sees first X-flare

On February 15, around 2am, SWAP and LYRA registered their first X-flare. The active region labelled NOAA AR 1158, and located close to the centre of the solar disk, produced an X2.2 flare peaking at 01:56 UT. It was associated with an Earth directed CME, which is expected to arrive at Earth on Feb 17. The flare was observed at 50ms cadence in the four LYRA bandpasses, showing the high energy burst in the Aluminium and Zirconium channels.

SWAP on the other hand, observed the flare evolution, the associated mass ejection, and a global coronal wave in its difference images.
