Geomagnetic information for selected areas along 71.5° geomagnetic latitude in 2014. Ggr and Gmag Lat/Long are geographic and geomagnetic latitude/longitude, respectively. H-field is the magnitude of the horizontal magnetic field and Midn MLT is the universal time for magnetic midnight in decimal hours.
