[more ▼] The strongest lines of Eu III, Gd III, Ce III, Sa III, and La III in the region λλ 3070-3300 are identified in the spectrum of α2 CVn. Their intensities and radial velocities undergo changes parallel to those of the lines of the corresponding singly ionized elements. Several unidentified lines in the blue-violet region are probably due to Dy III.
