LARGE-SCALE PHENOMENA AT THE SUN ASSOCIATED . WITH FILAMENT ERUPTIONS OUTSIDE ACTIVE . ... Considering the 12.09.1999 event as an example, we analyze manifestations of large-scale disturbances associated with coronal mass ejections (CMEs) caused by filament eruptions outside of active regions. ... The filament eruption occurred in relatively weak magnetic fields, but it was accompanied by larger-scale phenomena than flare events do. ...

... Determination of Black Hole Masses via Correlations between their X-Ray Spectral and Timing Properties " . ... This fact strongly support our theoretically motivated idea that low frequency QPO for a particular BH state is inversely proportional to BH mass.Based on our scaling technique, we determine BH masses in H1743-322, GX 339-4, XTE J1650-500, XTE J1859-226, 4U 1543-47, 4U 1630-47, using independently known masses of XTE J1550-564, GRO J1655-40 and GRS 1915+105 as references. ...

... There are preliminary series of photometric and radio spectral observations of the above-mentioned stars, archival data on the light curves of the stars, results of the search for OH and H 2 O maser emission in IRAS point sources that possess the IR parameters similar to Miras. ... The aim is a detailed study of the maser emission variability. ... In 1996-1997, astronomical observations of Mira Ceti-type stars (miras) were carried out in three spectral ranges: optical, infrared, and radio. ...

USING THE CORRELATION BETWEEN ISGRI SURVEY RESULTS AND OTHER CATALOGUES TO AID SOURCE IDENTIFICATION John B. Stephen, A. Malizia and L. Bassani IASF-INAF, Via P. Gobetti 101, 40129 Bologna, ITALY, E-mail: stephen@iasfbo.inaf.it ABSTRACT In order to help in the identification of INTEGRAL/ISGRI sources, we have developed a software package which allows a rapid and detailed cross-correlation to be performed between various source catalogues. ... We show below some preliminary results from this analysis. ...

... We apply Multichannel Singular Spectrum Analysis (MSSA, or extended EOF) technique to filter GRACE data and separate the principal components (PCs) of different periods. We performed data averaging over the large river basins of Russia. ... In every point ij on the map we have time series Aij(tk) of length N. The trajectory matrix for every XAij should be build and incorporated into large block matrix X as follows: X Aij Aij (t0 ) Aij (t1 ) .. ... Sum of PCs 1-10 for particular rivers basins. ...

... Spectra obtained with the 6-m telescope of SAO RAS are used along with archival data from Spitzer and several ground-based telescopes to infer a strength of PAH emission, age, properties of the UV radiation field, and metallicity of studied HII complexes. Physical properties (age, radiation field parameters, metallicity) are related to the F 8 /F 24 ratio used as a proxy for the PAH abundance in order to reveal factors that may influence the PAH evolution in HII complexes. ...
