Abstract

geomagnetic K-index, solar quiet day, geomagnetic stormIn this article, we present the origin of geomagnetic K-index.The International Association for Geomagnetism and Aeronomy (IAGA) recommends it for daily descriptions of geomagnetic field activity.The index is based on continuous measurements in a geomagnetic observatory on the Earth's surface.We carried out measurements in Slovene Istria, which enabled us to calculate the local geomagnetic index for Slovenia.In Discussion and Conclusions, we also present some drawbacks of the index and plans for our future activities in this field.geomagnetni indeks K, geomagnetno miren dan, geomagnetna nevihta V članku opisujemo izhodišča za oblikovanje geomagnetnega indeksa K, ki ga mednarodna organizacija IAGA (International Association for Geomagnetism and Aeronomy) priporoča za vsakodnevno opisovanje aktivnosti zemeljskega magnetnega polja.Indeks določamo na podlagi zveznih meritev na geomagnetnih observatorijih na površini Zemlje.Meritve smo začeli izvajati v slovenskem delu Istre, kar nam omogoča tudi izračunavanje lokalnega geomagnetnega indeksa K za Slovenijo.V Razpravi in zaključkih predstavljamo slabosti indeksa in svoje videnje nadaljnjega dela na tem področju.
