Using the 1-m telescope at Ritter Observatory, we took 36 observations of \zeta$^2$ Coronae Borealis with a fiber-fed echelle spectrograph. From these observations, \zeta$^2$ CrB was found to be a triple system and a new spectroscopic orbit was calculated. ... The inner binary`s center of mass (\zeta$^2$ CrB AB) describes a long-period single-lined variation identified with the outer binary. ... The inner binary possesses an essentially circular orbit $(e = 0.48)$. ...

Solar flares strongly influence interplanetary and terrestrial space by virtue of hard electromagnetic radiation, high-energy charged particles, shock waves and fast flows of plasma with magnetic field. Modern space observations demonstrate that the large-scale dynamics of flares is determined by fast magnetic reconnection at separators in the solar corona. ...

Next: Reduction procedure Up: Extinction and transformation Previous: Strategy . Standard stars can be included in the extinction solution, if one is careful. The problem is that there are usually appreciable ``conformity errors'' due to mismatch between the instrumental and the standard passbands [ 16 ]. ... Thus, it is wrong to assume that the transformation between the instrumental system and the standard system is exact, even if there were no measurement error in either system [ 1 ]. ...
