In July of 1931, on the eve of International Polar Year II, an Arctic flight of the Graf Zeppelin rigid airship was organized. This flight was a realization of the idea of F. Nansen, who advocated the use of airships for the scientific exploration of

Abstract In the course of the 2019−2020 round-the-world expedition of the oceanographic research vessel Admiral Vladimirskii, which repeated the route of F. Bellingshausen and M. Lazarev in 1820, a large volume of magnetic data was obtained, includ

Solar-Activity Cycles Reconstructed from Statistics on Polar Lights with Allowance for the Contribution of the Main Magnetic Field of the Earth in 1000–2000

Autor: N. G. Ptitsyna, I. M. Demina

Publikováno v: Geomagnetism and Aeronomy. 61:312-324

We examined cycles of solar activity reconstructed based on the number of auroras observed at the middle and low latitudes in 1000–1700. We used a wavelet analysis method. Variations in the Earth’s magnetic moment influence the propagation of cos

Reconstruction of the Solar Activity in 1000–1700 Based on Auroral Data with Allowance for the Contribution of the Main Magnetic Field of the Earth

Autor: N. G. Ptitsyna, I. M. Demina

Publikováno v: Geomagnetism and Aeronomy. 60:495-506

A new reconstruction of the number of sunspots (SN) in 1000–1700, along with possible errors, has been obtained based on an analysis of auroral observations at middle and low latitudes and data on the Earth’s magnetic field at that time. The inte

Publikováno v: Geomagnetism and Aeronomy. 59:147-154

In this work, geomagnetic cutoff rigidities are calculated in a model magnetosphere field on the world latitude–longitude 5° × 15° grid during the main phase of the magnetic storm of November 20, 2003. A decrease in geomagnetic thresholds (ΔR)

Variations in the Auroral Activity and Main Magnetic Field of the Earth over 300 years (1600–1909)

Autor: I. M. Demina, Marta Tyasto, N. G. Ptitsyna

Publikováno v: Geomagnetism and Aeronomy. 58:784-792

We estimate the contribution of the systematic component of the Earth’s main magnetic field (MMF), i.e., the main dipole, to the secular variation in the midlatitude polar auroras based on the archived data. It is found that the main features of th

Inverse problem for the current loop model: Possibilities and restrictions

Autor: Yu. G. Farafonova, I. M. Demina

Publikováno v: Geomagnetism and Aeronomy. 56:415-425

The possibilities of determining arbitrary current loop parameters based on the spatial structures of the magnetic field components generated by this loop on a sphere with a specified radius have been considered with the use of models. The model para
