The data were obtained by digitising and processing the original old records published in the yearbooks of this historical observatory. The term-day observations had been agreed for joint measurements by the observatories organised in the Göttingen Magnetic Union (GMU). Data of 120 term-days from January 1840 to December 1849 are published. The observations started at 10 p.m. of Göttingen Mean Time and lasted 24 hours. The interval between observations was 5 minutes (in April, June and July 1842 exceptionally 6 minutes). All time data were transformed into UT, based on the longitude of the Göttingen observatory, which was 9.950°. The time shift is thus 39'48''. The date in the term-day file name indicates the second day which involves substantial part of the observations (22 out of 24 hours). 14.416 14.416 50.086 50.086 14.416 50.086 1847-07-21T21:20:12 1847-07-22T21:20:12 190.0 190.0 time slice Clementinum Clementinum geomagnetic observatory in Prague 50.086 14.416 190.0 Geomagnetic observatory MAGOBS 577 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ DATE/TIME Date/Time http://en.wikipedia.org/wiki/ISO_8601 Time T http://dbpedia.org/resource/Time Hejda Pavel ph@ig.cas.cz https://www.ig.cas.cz/en/contact/staff/pavel-hejda/ 0000-0002-3576-5754 Date/Time Magnetic field, declination Decl deg Magnetic Field B Angle http://dbpedia.org/resource/Angle Plane Angle http://dbpedia.org/resource/Plane_angle Digitising and processing of historical records Hejda Pavel ph@ig.cas.cz https://www.ig.cas.cz/en/contact/staff/pavel-hejda/ 0000-0002-3576-5754 Decl [deg] Magnetic field, H-component H-comp nT Magnetic Field B Digitising and processing of historical records Hejda Pavel ph@ig.cas.cz https://www.ig.cas.cz/en/contact/staff/pavel-hejda/ 0000-0002-3576-5754 H-comp [nT] CurationLevelC Enhanced curation https://wiki.pangaea.de/wiki/Curation_levels citable author84893 author84894 author84895 curlevel30 event2985941 geocode1599 geocode1600 geocode1601 geocode8128 license21 method11867 method13829 param504936 param504937 pi84893 term43765 term43887 term43915 term43975 topotype9
