Appendix A: Other flares

thumbnail Fig. A.1

Light curves of several EVE lines during the X6.9 class flare on 9 August 2011. Irradiances are in 108 phot cm-2 s-1, time in UT. The dashed lines indicate the three regions selected (pre-flare, gradual phase peak, and gradual phase decline).

On 9 August 2011, the Sun produced the largest flare observed by EVE, an X6.9 class; MEGS-B did not observe this flare. Figure A.1 shows the light curves, while Fig. A.2 shows the spectra. Figures A.3 and A.4 show the light curves and the

spectra of the 6 Nov 2010 M5.4 class flare. Figures A.5 and A.6 show the light curves and the spectra of the smaller M2.0 class flare on 12 June 2010.
