Secular variations of the geomagnetic field and solar activity
An attempt was made to separate the secular fluctuations created by external sources, according to the observatories Nur Miyar Vee, Lervik, Leningrad, Nimek, Belsk, Hart Land, Kiev, Lviv, "Sham Bon-la-Foret", "Odessa", "Surlarly", "Coimbra". It is shown that t...
