Un nou estudi publicat per científics del Kyoto-Kyushu Research Team el passat 21.12.2015 a la revista Journal of Geophysical Research, afirma haver resolt el misteri de ruptures de les aurores - la formació de les subtempestes d'aurores boreals amb sobtats esclats de brillantor. L'estudi tira per terra les teories existents sobre el mecanisme que es troba darrere d'aquest fenomen.
Caithness: Night of the Northern Lights, 27-28 February 2014, by Maciej Winiarczyk (Caithness Astronomy Group) at youtube.
On 25th February 2014 Sun produced X4.9 flare which on 27th February caused G2 (KP 6) geomagnetic storm on Earth. It was the brightest aurora display so far during this solar maximum which I could witness with auroral displays overhead in the far north of Scotland. This short movie illustrates what has been seen from latitude 58.3 degrees north.
