On 7 December 2000, TV ASC camera in Barentsburg (Svalbard) observed pre-noon (at 09:00–10:00 MLT) rayed auroral arcs, which occurred at the pole-ward edge of the auroral oval after an IMF transition from B y -dominated ( B y = + 8.8, B z = + 4.3) to strongly northward dominated ( B y = + 2.7, B z =...
