Abstract The rapid changes of magnetic fields associated with large, isolated perturbations amplitudes |Δ B | hundreds nanotesla and 5‐ to 10‐min periods can induce bursts geomagnetically induced currents that harm technological systems. This paper presents statistical summaries the characteristics nightside perturbation events observed in Eastern Arctic Canada from 2014 through 2017 using data stations are part four magnetometer arrays: MACCS, AUTUMNX, CANMOS, CARISMA, covering a range...

Using observations from the IMAGE magnetic observatories and station for recording geomagnetically induced currents (GIC) in electric transmission line 2015, we examine relationships between geomagnetic field GIC variations. The intensity is highly correlated (R>0.7) with variability |dB/dt| closely variations time derivatives of X Y components. Daily mean have a wide night maximum, associated electrojet, morning presumably caused by intense Pc5–Pi3 pulsations. We constructed regression...

A nowcasting and even forecast of the auroral oval position intensity is a highly needed resource for practical applications.The region with high level ionospheric plasma turbulence, which provokes malfunctions radio communication navigation satellite systems, most intense irregular electrojet exciting geomagnetically induced currents (GICs) in electric power lines.We have elaborated web service (http://aurora-forecast.ru) continuous nowcasting, visualization short-term auroras.The...

The geomagnetically induced currents (GICs) in extended grounded technological systems are driven by telluric electric fields the rapid changes of geomagnetic field. paper is concerned with research on approach to diagnostics GIC power transmission lines northwestern Russia based data from IMAGE magnetometers. Based results statistical and correlation analysis objective function (the level recorded at Vykhodnoy transformer station) nearby magnetometers, features that best characterize target...

An interactive computer model of a short-term (with horizon 30–70 min) forecast aurora intensity has been developed in the form web-based geoinformation system. The OVATION-Prime empirical is used as basic software, which establishes statistical relationships between parameters solar wind, interplanetary magnetic field, and auroral particle fluxes. On basis this model, system built simulates spatial planetary distribution probability observing auroras number accompanying quantities. Data...

One of the main tools for recording auroras is optical observation sky in automatic mode using all-sky cameras. The results observations are recorded special mnemonic tables, ascaplots. Ascaplots provide daily information on presence or absence cloud cover and various parts traditionally used to study distribution a given spatial region, as well calculate probability their other regions accordance with level geomagnetic activity. At same time, processing ascaplots currently carried out...

Analysis of well-known services for monitoring geophysical parameters in the auroral oval area has revealed a number disadvantages, which are typical and, principle, repeating from implementation to implementation.They inability dynamically scale and add auxillary layers; mall displayed parameters; lack data on current state space weather basic tools spatial analysis visualized parameters, etc.Thus, paper is concerned with an approach (architecture its software implementation) create...

Due to the established and well-studied effects of impact space environment on technical objects high-latitude infrastructure, which are most clearly manifested during periods magnetic storms, problem creating an effective open system for visualization analytical control geomagnetic field its variations parameters, especially polar regions, is quite acute today.In this paper, using data from observatories variation stations included in SuperMAG project (https://supermag.jhuapl.edu/),based...

Today intensive development of systems and technologies for registration the Earth’s magnetic field parameters causes an exponential increase geomagnetic data quantity, mainly collected by ground stations. Imperfection applied equipment enabled channels information transfer leads to presence omissions in registered time series. Along with spatial anisotropy it creates a serious obstacle processing data. Russian foreign scientific organizations are used recover missing linear interpolation....

In the course of manufacturing and operation, there can appear cracks in load-carrying metal structures which are hard to be detected till a definite moment. That is why designing structures, it necessary ensure their durability during possible existence up next routine inspection structure. For prognostication structure with crack, research coefficients stress intensity on end-element models crack-like defects different length carried out. As result this, procedure for definition...
