Measurements of the composition and energy spectra of ions near 1 MeV/nucleon during the November 1977 solar flare particle event are presented using data from the Low Energy Charged Particles experiment on Voyager 2. The O/He and Fe/He flux ratios, evaluated over equal energy/nucleon intervals, decrease monotonically from maximum values near event onset. The O/C ratio declines only slightly during the event and the He/H ratio reaches its maximum value near time of maximum intensity. The spectral indices of all species have minimum values at event onset and increase during the event, showing the effect of velocity dispersion.
