Poyasnenie: Poslednee vremya aktivnoe Solnce, vybrasyvalo v nashu storonu intensivnye potoki chastic solnechnogo vetra i oblaka plazmy, chto privodilo k poyavleniyu velichestvennyh polyarnyh siyanii. No vmeste s tem, vse bol'she nakaplivaetsya strannyh nablyudenii, vypolnennyh priborom LASCO na bortu kosmicheskoi solnechnoi i geliosfernoi observatorii SOHO, kotorye govoryat, chto est' takzhe veshestvo, kotoroe techet v storonu Solnca, nachinaya s vysoty bolee 2 millionov kilometrov nad ego vidimoi poverhnost'yu. Dvizhenie temnogo oblaka, dostatochno otchetlivogo, chtoby ego mozhno bylo obnaruzhit' na fone istekayushego solnechnogo koronal'nogo veshestva, napravleno k Solncu, chto proslezhivaetsya, na predstavlennyh snimkah (podvergnutyh slozhnoi obrabotke) sdelannyh s raznicei v chas. Izluchenie solnechnoi poverhnosti, kotoraya oboznachena zheltym krugovym sektorom v nizhnem pravom uglu, blokiruetsya krugloi zaslonkoi. Soprotivlyayas' solnechnomu vetru, imeyushemu skorost' okolo 120 kilometrov v sekundu, oblako priblizhaetsya k Solncu so skorost'yu v 50–100 kilometrov v sekundu. Takie oblaka, inogda poyavlyayushiesya s intervalom vsego okolo chasa, vidimo, prityagivayutsya szhimayushimsya magnitnym polem, a ne odnoi tol'ko siloi tyazhesti. Issledovateli teper' rabotayut, nad tem, chtoby vyyasnit' svyaz' etih udivitel'nyh nishodyashih potokov s solnechnym vetrom i magnitnoi obstanovkoi na Solnce.
