Abstract. We study the directional structure of the 1-minute magnetic variations and demonstrate their polarization-like asymmetry: statistically these directions are close to certain 2D plane in 3D space and the orientation of such a plane depends on the observatory location. We describe the method of the magnetic data processing and some partial results, however in this publication we are avoiding the reasonings concerning the physical origins of the detected effect and its consequences for the observatory data 5 analysis in general.

Short summary
Magnetic field of the Earth is continuously measured by a network of observatories. It implies application of mathematical and computational technologies for geomagnetic data processing. Actual conditions in which observations are performed should be also considered. Effective identification of noise and elimination of its influence on final data is an important part of the data processing. An original approach for magnetic data processing and some partial results are discussed in this paper.
