Magnetic turbulence in the cusp region: 3D spectra and vortex cascades
Romanov, S. A.
Cluster satellite measurements that were carried out in the region of the altitudinal cusp in the Earth's magnetosphere and adjacent regions were processed to yield the dynamic pattern of the 3D spectra of magnetic field oscillations in the space of wave vectors, with wave numbers ranging from 0.002 to 0.5 rad/km. The anisotropic properties of spa…
On the possibility of coupling satellite and ground-based optical measurements in the region of pulsating auroras
Safargaleev, V. V.; Shibaeva, D. N.; Sergienko, T. I. +1 more
The possibility of comparing in detail CLUSTER satellite data with data on pulsating spots registered with a TV camera at the Lovozero Observatory when the satellite crossed the magnetospheric region related to the camera's field of view is discussed. The satellite ionospheric projections were calculated using the T89, T96, and T01 models. It was …
New method for separating K- and F-corona brightness based on LASCO/SOHO data
Fainshtein, V. G.
A relatively simple (in technology) method for separating K- and F-corona brightness based on LASCO data, which makes it possible to obtain the latitude distribution of this brightness in the field of view of the LASCO C2 and C3 coronographs at any instant for which white light corona images are available, has been proposed. It has been estimated …
Correlation between the parameters of coronal mass ejections and features of their propagation in the corona with the large-scale structure of the solar magnetic field
Ivanov, E. V.; Fainshtein, V. G.; Rudenko, G. V.
Correlation between the parameters of coronal mass ejections (CMEs) that are detected on the LASCO coronographs and are associated with eruptive prominences and the distances of CME axes from the coronal streamer belt has been analyzed. The deviations of CME trajectories from the radial direction have been investigated.
Space projections on solar-terrestrial physics
Zelenyi, L. M.; Kuznetsov, V. D.
An overview of the current status of research in the field of solar-terrestrial physics conducted by space agencies of various countries is given. The main results of current (Ulysses, SOHO, TRACE, RHESSI, Hinode, and STEREO) and completed (Coronas-F and others) missions as well as the scientific goals and objectives of space projects being prepar…
Ejection and descent of matter in the solar atmosphere
Divlekeev, M. I.
The descent and ejection of matter in the solar atmosphere observed in the CaII 8498-Å line have been studied. In the NOAA active region no. 10 792 on July 30, 2005 before the flare, the dense cold gas cloud descended with a ray velocity of ∼8 km/s and then ascended in the impulsive phase. The plasma ascended with an acceleration reaching 0.4 km/s…
