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.
