Abstract: A set of the white-light images was used to perform relative photometry of the July 11, 1991 eclipse corona. The observed global form of that day corona was found to be rather unusual for the actual solar cycle phase. In this relation, the recently calculated coronal magnetic field structures and strengths are presented and discussed. An idea on the close relation between the observed global form of the corona and the presence of the individual coronal structures around the solar limb, on the one hand, and the calculated magnetic field topology and strength, on the other hand, is supported and found to be of great interest.
