Flare spectral variations from the EVE MEGS Flare spectral variations from the EVE MEGS A channel (6–37 nm) for the C8.8 flare on 2010 May 5 as adapted from Woods et al. (2011). A The pre-flare spectrum. B–D The variability between the pre-flare irradiance and the main phase, coronal dimming, and EUV late phase, respectively. These results used 5-min averages taken at the times indicated in Fig. 8 as vertical dashed lines
