RESUMO

Quasi-periodic variations in the geomagnetic field within the range of periods 1 to 1000 s as observed near Kharkiv (Ukraine) in 2002 thru 2011 are analyzed with respect to their relation to solar terminator passage through the magnetoconjugate region. The observations have been made for the summer and winter seasons. Quasi-periodic perturbations in the geomagnetic field have been detected which were in advance by 80 to 100 min of the time moment of the solar terminator passage over Kharkiv at the 100 km altitude. The characteristic period of the perturbations was 10 to 12 min, duration 50 to 60 min and amplitude 1 to 2 nT. It is vindicated that the perturbations are transported from the magnetoconjugate region by slow magnetoacoustic waves.
