Interstellar polarization at high galactic latitudes from distant stars. VI. Extended polarization map and connection with the local spiral structure.
We present new interstellar polarization measurements for 116 stars athigh galactic latitudes. Our data show that Markkanen's cloud -- themain polarization structure seen in the North Galactic Pole area (b >75 degr) extends further towards lower latitudes. Especially, we havefound a new dust formation in the area 35 degr < l < 45 degr, 57degr < b < 63 degr. Interstellar polarization in this part of thesky peaks at 0.7%, which gives a lower limit to the extinctionAV > 0.23m. Polarization vectors in this cloud are verywell aligned along the direction of l = 50 degr. On the IRAS 100 micronmap this dust structure shows up as a bright emission area. We discussthe new polarization map extending from circumpolar to lower latitudesand point out features which suggest that Markkanen's cloud may be apart of the dust lane in the inner edge of the local spiral or spur.

The Tokyo PMC catalog 90-93: Catalog of positions of 6649 stars observed in 1990 through 1993 with Tokyo photoelectric meridian circle
The sixth annual catalog of the Tokyo Photoelectric Meridian Circle(PMC) is presented for 6649 stars which were observed at least two timesin January 1990 through March 1993. The mean positions of the starsobserved are given in the catalog at the corresponding mean epochs ofobservations of individual stars. The coordinates of the catalog arebased on the FK5 system, and referred to the equinox and equator ofJ2000.0. The mean local deviations of the observed positions from theFK5 catalog positions are constructed for the basic FK5 stars to comparewith those of the Tokyo PMC Catalog 89 and preliminary Hipparcos resultsof H30.
