Fraquelli, D. A. Abstract Spectrophotometry of the Ha emission line in the spectrum of HR 1099 (= HD 22468= V7 11 Tauri) was obtained during the radio flare of February 1978. The profiles observed during the flare have higher peak intensities and larger equivalent widths than profiles obtained outside of the flare at approximately the same orbital phases. Both the general shapes of the profiles and the equivalent widths appear to correlate with the radio flux. A preflare profile exhibits a flare-type profile, suggesting that radio outbursts in RS CVn systems may be preceded by Ha enhancement.
