... A ray obliquely incident at the cylinder scatters on the surface of a cone (in the far zone) mainly in the forward direction. The results for the cylinder with the radius equal to the wavelength of incident radiation multiplied by 5 / pi ( x =10), the refractive index m=n+k i=1.33 and the angle between the symmetry axis of the particle and the wave-vector of incident radiation alpha =45 o were obtained with one of the codes presented in the DOP.

Compilation of position angles . ... Search an object in the catalogue of position angles . This catalogue (table a103 in the database) presents the compilation of the position angles for galaxies. The position angle of the major axis is counted in degrees (0 to 180) from the North to the East: PA=0 corresponds to a galaxy whose longest axis is oriented North-South. Galaxies are not pure ellipsoids and therefore the position angles may varies with the considered surface brightness level. ...

... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...

Mal Ruderman (KIPAC, Stanford) . What do we see when we look at the surface of a neutron star from a great distance? ... The new point that is made is a consequence of near-relativistic electron-positron flows expected in the near-magnetosphere's of "young" (not older than about a million years) neutron stars. Because of cyclotron resonance scattering by these pair-flows on surface X-ray and UV emission, we do not see unprocessed suface emission. ...
