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…
