We continue to study the physical processes occurring during the August 17, 2001 magnetospheric storm by analyzing the dynamics of the intensity of field-aligned currents (FACs) in Iijima—Potemra Region 1 in the polar ionospheres of the two hemispheres ...

Chromospheric K CaII telescope of Baikal Astrophysical Observatory. New light
In recent years, most results of CaII studies of the solar chromosphere in H and K lines have been based on observations with narrow passband filters.

Scientific goals of optical instruments of the National Heliogeophysical Complex
Studies of the upper atmosphere have to be performed using optical photometric and spectrometric means. Modern devices allow precise photometry of the glow of the night atmosphere — airglow — with high temporal spatial and spectral resolution.

Galactic cosmic rays and solar energetic particles (SEPs) with energies larger than 100 MeV/n are able to penetrate and charge the test masses of the LISA experiment. As this process constitutes one of the major sources of noise for the experiment, a small telescope of silicon detectors will be located on board the LISA PathFinder and, possibly, the ...

Multijunction Solar Cells on Epitaxial Templates [PDF]
Future ultrahigh efficiency multijunction solar cells will employ designs that feature three or four or more subcells utilizing lattice-mismatched structures to achieve an optimal band gap sequence for solar energy conversion.

Project of the Large Solar Telescope with mirror 3 m in diameter
One of the most important problems of modern solar physics is the observation of the small-scale structure of the solar atmosphere at various heights (including the chromosphere and corona) in different spectral lines.

Improved equivalent circuit and analytical model for amorphous silicon solar cells and modules [PDF]
An improved equivalent circuit for hydrogenated amorphous silicon (a-Si:H) solar cells and modules is presented. It is based on the classic combination of a diode with an exponential current-voltage characteristic, of a photocurrent source plus a new ...

PECULIARITIES OF 630.0 AND 557.7 NM EMISSIONS IN THE MAIN IONOSPHERIC TROUGH: MARCH 17, 2015
Peculiarities of 557.7 and 630.0 nm emissions observed in the second step of the magnetic storm main phase at the mid-latitude observatory Tory (52° N, 103° E) on March 17, 2015 are compared with the changes in ionospheric parameters above this station ...
