About Aurora Islands (Islas Aurora) – Phantom Falkland Shag Rocks of the South Atlantic
Aurora Islands – phantom archipelago 4 islands reported 1762 by Spanish ship Aurora (José de la Llana) at 53°S 48°W 300 km north of Shag Rocks, charted by Weddell, Morrell and Argentina until 1856–1870s surveys proved empty South Atlantic at 4050 m depth. Their persistent appearance (1762–1856) anchored Argentine sovereignty claims before 1820 Falklands. Weddell's 1822 sighting of shag-covered rocks likely was Shag Rocks (Black Rock) mis-located 20 km due to chronometer error. Antarctic phantom archipelago of the Scotia Sea.
Why it mattersCase-study for Scotia Sea phantom persistence and early Argentine Antarctic claim cartography.
