Top: schematic 2−10 keV X-ray light curve during the 1998−2014 events (Corcoran et al. 2014a)5. Bottom: the He ii equivalent widths for the same time span. The vertical lines are to aid the comparison of the decline and rise of the X-rays with the He ii maxima. Unfortunately, we have no data at the expected later phase of the second He ii flare for events prior to 2009.
