The Inter-regional Geomagnetic Data Center of the Russian-Ukrainian INTERMAGNET segment is operated by the Geophysical Center of the Russian Academy of Sciences (GC RAS). Geomagnetic data are transmitted from observatories and stations located in Russia and Ukraine. The particular feature of the Center is the automated system for real-time recognition of artificial (anthropogenic) disturbances in incoming data. Being based on fuzzy logic approach, this quality control system facilitates the preparation of the definitive magnetograms from preliminary records carried out by data experts manually. The collected geomagnetic data are stored using relational database management system. The geomagnetic database is intended for storing both 1-minute and 1-second data. The results of anthropogenic disturbance recognition are also stored in the database.
