The methodology of a processing of photographical observations of the green coronal spectral line at 530.3 nm (FeXIV) with an aim to determine rotational properties of the solar corona is described in the paper. Selected patrol photos of the line taken in the coronal station at the Lomnicky Peak (Astronomical Institute of the Slovak Academy of Sciences) are used for a. computation of the rotational velocity of the solar corona according to Doppler displacements of the coronal line. We intend to explore a hypothetical westward wind in the solar corona, which was revealed by Evershed (1929) and investigated later by Livingston (1971). However, since the processed patrol photos are not enough, we are not able yet to evaluate the rotation of the solar corona.
