Oscillation properties in two sunspots and two facular regions are studied using Solar
Dynamics Observatory (SDO) data and ground-based observations in the Si i 10827Å and …

A method for measuring the differential ray velocity and magnetic field strength on the sun in
the modulationless mode with the use of a diffraction-grating spectrograph and CCD-based …

We analyze the oscillations of the H α profile width based on our observations of the
chromosphere at the base of solar coronal holes. The maximum oscillation amplitude …

Cosmological large numbers are studied using dimensional analysis. Expressions linking
cosmological parameters with fundamental constants of the microworld are proposed. The …

Observations of oscillations in the penumbras of seven sunspots are analyzed. High-
sensitivity differential measurements of the line-of-sight velocity (11 time series) and …

The Atmospheric Chemistry Experiment (ACE) is the mission selected by the Canadian
Space Agency for its next science satellite, SCISAT-1. ACE consists of a suite of instruments …

This paper is devoted to the study of spatial characteristics and height stratification of the 4-
min oscillations. The line-of-sight velocity observations were made using a local differential …

An analysis is made of vector-magnetograms and of the velocity network associated with
super-granulation in the photosphere, in the region of a quiescent filament. Observational …

In this paper we consider the possibility of modulationless measuring the magnetic-field
strength and the differential line-of-sight velocity, based on using a diffraction spectrograph …

Выполнен анализ колебаний ширины профиля спектральной линии Н по наблюдениям
хромосферы в основании солнечных корональных дыр. В среднем по 10 временным …
