cds-question@unistra.frpolarimetrynorth-galactic-poleWe present new interstellar polarization measurements for 116 stars at high galactic latitudes. Our data show that Markkanen's cloud - the main polarization structure seen in the North Galactic Pole area (b>75{deg}) extends further towards lower latitudes. Especially, we have found a new dust formation in the area 35{deg}<l<45{deg}, 57{deg}<b<63{deg}. Interstellar polarization in this part of the sky peaks at 0.7%, which gives a lower limit to the extinction A_V_>0.23mag. Polarization vectors in this cloud are very well aligned along the direction of l=50{deg}. On the IRAS 100 micron map this dust structure shows up as a bright emission area. We discuss the new polarization map extending from circumpolar to lower latitudes and point out features which suggest that Markkanen's cloud may be a part of the dust lane in the inner edge of the local spiral or spur.2002A&A...384.1050Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/384/1050CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/372/276 : Polarization catalogue for NGP area (Berdyugin+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/384/1050https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/384/1050http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/384/1050https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/384/1050https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/384/1050http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/384/1050GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/384/1050/table1 (New polarization measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/384/1050/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/384/1050/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/384/1050/table1?GETtext/xml+votable180.050000true181.34483931.2103250.0055555555555555565/6971 6/5396 5399 5442 8423 8432 8445 8611 8620 8623 8627 8785 8791-8792 8808 8815 8831 8887 8898-8900 8905 8932 8935 8944 8948-8949 8966-8967 8983 8995-8998 9004 9008 9011 9014 9016 9018 9024 9058 9097 9113-9114 9123 9127 9139 9160 10320-10321 10434 10628 10636 10671 10843 10845 10861 10904 10945 11016-11017 27852 27858 27861 27864 27873 27876 27878-27879 27881 27890 27892 27896 27900 28015 28056-28057 28101 28229 28372 28383 28523 28544 28551 28604https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/384/1050?format=asciiOpticaldefaultJ/A+A/384/1050/table1New polarization measurementsrecnoRecord number assigned by the VizieR team.
