Analysis and results of cooperative magnetographic measurements. I - Correction, comparison and discussion of measurements
Abstract
On June 24, 1983 cooperative magnetographic measurements were made with the vectormagnetographs of the Sayan Observatory (Irkutsk) and the Potsdam Solar Observatory "Einsteinturm" and with the longitudinal magnetograph of the Ondřejov Observatory. Additionally, the maximum field strengths in the sunspot were measured with the photographic method. A comparison of nearly simultaneous magnetograms shows a good correspondence in general. Regarding the magnetic field distribution the magnetograms reflect a substantial nonsymmetric structure in the spot under study. The magnetic field lines tend to concentrate into several flux tube clusters.
