MULTI-FREQUENCY OBSERVATIONS OF THE POLAR RADIO STRUCTURES A. Riehokainen1 , A.G. Tlatov 1 2 2 Tuorla Observatory 21500, Piikkio, Finland; Pulkovo Astronomical Observatory, St. Petersburg, Russia alerie@utu.fi In this work we present a comparison of the enhanced temp erature regions (ETRs) in the radio emission of the Sun with other manifestations of solar p olar structures over some days in 2003-2005. ... We compared our radio data with different SOHO/EIT and SOHO/MDI images for the same p erio ds. ...

Spectropolarimetry and modeling of Galactic Wolf-Rayet star WR156 O LGA M A RY E VA Special Astrophysical Observatory RAS; olga.maryeva@gmail.com For the first time spectropolarimetric observations of Wolf-Rayet star WR156 (WN8h sub-class) were conducted. ... This polarization is, most probably, has an interstellar origin, as its magnitude and orientation are similar to the ones of field stars. ... By its parameters WR156 is similar to other WN8h stars, displaying the line effect. ...
