Simultaneous Observations with a Tunable Filter and the Echelle Spectrograph of the Vacuum Tower Temportant characteristics of the telescope are described. The science observing programs were dedicated to the measurements of small scale magnetic structures and the velocity fields in both horizontal coordinates and at different heights in the solar atmosphere. Narrow band filtergrams in left and r

Aspects of the Present Heliospheric Research,he fact that counts most in this context is the evident peculiar motion of the sun relative to the ambient interstellar medium. An interesting puzzle thus is how the inner heliospheric plasma properties reflect this fact. Here we briefly will follow the lines by which the interstellar medium influen

First Results from the X-Ray Astronomy Mission ROSAT,urce in 1962. Collimated counters have been used exclusively in the first 16 years, and they are still the only way to perform X-ray observations at energies above about 20 keV. At lower energies imaging telescopes offer the opportunity to take true pictures of celestial sources at a significantly r

Magnetic Field Measurements on Cool Stars, overview the basics underlying the measurement of magnetic fields on cool stars are briefly introduced. The special role played by the sun in the study of stellar magnetism is pointed out and illustrated with the help of two examples. Stellar measurements in circularly polarized light are discussed
