Visual polarization measurements in the Cepheus flare
We present polarization measurements on a stellar sample located in alarge area in Cepheus. The observations were made with the 2-m telescopeat the Pic du Midi (France), around 4350 A and with an accuracy of thepolarization degree of the order of 0.0001. At large scales, we findthat the galactic magnetic field as given by the direction of thepolarization (alignment of the dust) is, roughly speaking, parallel tothe galactic plane in the Cassiopeia cloud, with a scale size of theorder of 100 pc, while it is turned by about 90 in the Cepheus cloud. Atsmall scales, in both the Cepheus and the Cassiopeia clouds, the COcontent has little correlation with the degree of polarization.

Locations of the components of triple star systems north of +70 deg
Micrometric measurements of triple systems north of +70 deg declinationwere made with the 10.5-inch Fraunhofer refractor of Munich UniversityObservatory. Absolute positions of all measured components were derivedby using the positions of the main stars as given in the catalog AGK3and, in some cases, also in the SAO-catalog.
