Scientific paper

It is found that the profile changes observed for the UV emission lines
L-alpha, C IV 1549, and Mg II 2798, in the Seyfert 1 galaxy Fairall 9
occur mainly near the line center for L-alpha and C IV and in the wings
for Mg II. These resuls indicate that the broad line region has a
complex structure, possibly with nonspherical components.
