| Abstract: |
Spectroscopic observations of II Pegasi are reported with particular attention given to flares observed in the He D3 emission, Balmer line ratios, and in comparisons of H-alpha and H-beta. A flare in progress was detected, and comparisons with an earlier harder flare shows that large flares can reach maximum intensity in optical lines after more than six hours. The possibility of small amplitude variations of the minimum emission and random emission events is set forth to describe the Balmer line modulation. |
