摘要：

Using the results of geomagnetic monitoring at the Mikhnevo geophysical observatory and spectral analysis methods, the spectral harmonics of geomagnetic variations were studied in the period range from 12 to 17 days. We have highlighted: harmonics associated with a variation in solar activity; harmonics due to the modulation of shorter-period variations by the long-period ones; harmonics close to periods of tidal waves, and harmonics close to the period of the atmospheric planetary 16-day wave. Comparative analysis of the spectral composition in summer and winter for a period of low solar activity were carried out.
