Astronomicheskaya nedelya s 4 po 10 oktyabrya 2021 goda1.10.2021 7:01 | Aleksandr Kozlovskii
Na dannoi nedele 6 oktyabrya Luna (F= 0,01+) proidet severnee Merkuriya i Spiki. 8 oktyabrya Mars vstupit v soedinenie s Solncem, a Luna (F= 0,07+) dostignet perigeya svoei orbity na rasstoyanii 363388 km ot centra Zemli. 9 oktyabrya nastupit maksimum deistviya meteornogo potoka Drakonidy (ZHR= 20 - 100), a Luna (F= 0,15+) okazhetsya v nishodyashem uzle svoei orbity. V etot zhe den' Luna (F= 0,15+) proidet severnee Venery, a Merkurii proidet nizhnee soedinenie s Solncem. 10 oktyabrya dolgoperiodicheskaya peremennaya zvezda X Zmeenosca dostignet maksimuma bleska (6m), a Luna (F= 0,2+) proidet severnee Antaresa.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 27 gradusov, a dolgota dnya na toi zhe shirote - do 10 chasov 50 minut. Vidimyi diametr Solnca uvelichivaetsya do 32,04 minut dugi, a dvizhetsya ono po sozvezdiyu Devy. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 6 oktyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya L'va, Devy, Vesov, Skorpiona i Zmeenosca, izmenyaya fazu ot 0,07- do 0,25+ i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii L'va. V sozvezdie Devy tonkii lunnyi serp voidet pri faze 0,03- 4 oktyabrya. V etom sozvezdii 6 oktyabrya Luna primet fazu novoluniya i proidet v etot den' severnee Marsa i Merkuriya. 7 oktyabrya pri faze 0,01+ rastushii serp proidet severnee Spiki i ustremitsya k sozvezdiyu Vesov, v kotoroe voidet pri faze 0,04+ 8 oktyabrya. Zdes' Luna probudet do 9 oktyabrya, kogda dostignet sozvezdiya Skorpiona pri faze 0,13+. V etot zhe den' lunnyi serp pri faze 0,14+ proidet severnee Venery, a 10 oktyabrya (F= 0,18+) vstupit v sozvezdie Zmeenosca, nablyudayas' severnee Antaresa. Fazy Luny na dannoe vremya i na budushee.
Iz planet Solnechnoi sistemy: Merkurii ne viden, a Veneru mozhno naiti na vechernem nebe. Mars ne viden, a Yupiter i Saturn nablyudayutsya vecherom i noch'yu. Uran i Neptun mozhno nablyudat' v binokl' vsyu noch'. Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v pechatnoi versii v AK_2021 na http://www.astronet.ru/db/msg/1704127.

Iz komet hvostataya strannica P/Churyumov-Gerasimenko (67P) s bleskom okolo 10,5m peremeshaetsya po sozvezdiyu Tel'ca. Karty putei komet i asteroidov na mesyac imeyutsya v KN na sentyabr', a na drugie periody - v Astronomicheskom kalendare na 2021 god.

Sredi asteroidov naibolee yarkoi na dannoi nedele budet Vesta (7,9m) v sozvezdii Vesov.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: V Severnoi Korony 8,2m - 5 oktyabrya i X Zmeenosca 6,8m - 10 oktyabrya.
