Abstract. We present high-resolution spectral observations, covering the entire optical region (3800-9000 °A),
of a solar flare observed during a multi-wavelength campaign. The flare, recorded on 2002 January 11, was a
medium solar flare event (GOES class C7.5). The spectral observations were carried out using the Hamilton echelle
spectrograph on the coudŽe auxiliary telescope at Lick Observatory and with the Coronal Diagnostic Spectrometer
