Sellest ajast alates on ESA nelik \u2013 tuntud nimede Salsa, Samba, Rumba ja Tango all \u2013 lennanud Maa \u00fcmber formatsioonis. M\u00f5nikord on nad viibinud planeedi magnetv\u00e4ljas.

Virmalised tekivad siis, kui P\u00e4ikesest p\u00e4rit \u00fclikiired osakesed p\u00f5rkuvad meie planeedi magnetv\u00e4ljaga.
