Nad yuzhnym polyarnym siyaniem

Perevod: Vol'nova A.A.
Poyasnenie: 29 maya Mezhdunarodnaya kosmicheskaya stanciya proletala na vysote 350 kilometrov nad yuzhnoi chast'yu Indiiskogo okeana. Odin iz astronavtov na bortu stancii posmotrel na yug, i vot chto on uvidel. Ego vzoru predstala ogromnaya perelivayushayasya zelenaya lenta. Eto vsem izvestnoe yavlenie nazyvaetsya yuzhnoe polyarnoe siyanie (po-angliiski eshe govoryat "southern lights", chto doslovno oznachaet "yuzhnye ogni"). Takie zhe svetyashiesya vspolohi chasto nablyudayut i v severnyh shirotah — eto horosho znakomoe nam severnoe polyarnoe siyanie. Nevazhno, voznikaet siyanie na severe ili na yuge — prichina u nego vsegda odna i ta zhe. Vysokoenergichnye zaryazhennye kosmicheskie chasticy zahvatyvayutsya magnitosferoi Zemli i vzaimodeistvuyut s molekulami atmosfery vblizi polyusov. Harakternoe zelenoe svechenie prihodit s vysoty bolee 100 kilometrov ot vozbuzhdennyh atomov kisloroda. Po-vidimomu, polyarnoe siyanie 29 maya bylo vyzvano vzaimodeistviem magnitosfery Zemli s koronal'nym vybrosom, kotoryi proizoshel na Solnce 24 maya.
