Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... One of the rarest but most interesting effects which can be observed with the Irkutsk IS radar is anomal high power signal registraion(coherent echo) due to strong magnetic storms. ... These signals are formed at E-layer heights in the presence of a strong electric field which causes particles to drift. ...

... Our scientific interest is an accuracy of asteroid CCD observations obtained by amateurs and professional astronomers all over in the World. ... These data help us to analyse an accuracy of real CCD positions in the MPC Database. ... Do you test your observations of the small Solar System bodies permanently before sending them to the International Minor Planets' Center? ... Do you know a real accuracy of your positional CCD-observations in comparison with the other observatories' one ? ...

In the scalar Helmholtz equation the variables are separated in 11 physically interesting coordinate systems [ 55 ], however for the vector field containing 3 scalar functions, the complete separation of variables is possible only in 6 systems: Cartesian, 3 cylindrical, conical and spherical ones ([ 55 ], Ch.13). Therefore, the formal solution suggested in 1927 by F. Moeglich [ 368 ] for the spheroidal coordinates was practically usefulness until the work of Sh. ...

PENTICTON SOLAR RADIO FLUX VALUES (from SGD Explanation of Data Reports) Daily Solar Flux Values - Penticton -- Daily measurements of the integrated emission from the solar disc at 2800MHz (10.7cm wavelength) have been made by the National Research Council of Canada since 1947. ... The data are tabulated in two forms: the "observed flux" (S), and the "adjusted flux" (Sa). ... The "observed flux" values are useful in ionospheric physics and other terrestrial consequences of solar activity. ...

Summary of A. Skop enkov's prop osal This proposal concerns the classical Knotting Problem in topology: classify embeddings of a given space into another given space up to isotopy. ... The Knotting Problem is known to be hard. ... The Knotting Problem is most interesting for manifolds of dimension at most 4, because embeddings of such manifolds often appear in other branches of mathematics and its applications. ... For N not a homology sphere until 2005 no description of the orbits was known. ...

... Moon Phase below . ... ARTICLE: Why the moon always shows us the same face . ... Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...
