Example of EUV spectrum observation. The EUV spectrum at the GOES/XRS-B peak time (18:52 UT) was observed by the SDO/EVE MEGS-A for the M9.9-class flare on January 1, 2014. This EUV spectrum is subtracted non-enhanced value (at 18:00 UT) from the value of each wavelength before the flare as the background. The EUV flare lines focused on in this study are indicated by vertical dotted lines
