Astronomicheskaya nedelya s 18 po 24 oktyabrya 2021 goda Astronomicheskaya nedelya s 18 po 24 oktyabrya 2021 goda
15.10.2021 7:01 | Aleksandr Kozlovskii

Na dannoi nedele 18 oktyabrya Merkurii i Yupiter dostignut stoyaniya s perehodom k pryamomu dvizheniyu. 21 oktyabrya nastupit maksimum deistviya meteornogo potoka Orionidy (ZHR= 15), a Mars proidet v 2,6 gr. severnee Spiki. V etot zhe den' Luna (F= 0,98-) proidet yuzhnee Urana. 23 oktyabrya Luna (F= 0,94-) proidet yuzhnee Pleyad bliz voshodyashego uzla svoei orbity. 24 oktyabrya Luna (F= 0,88-) proidet severnee Al'debarana, a pri faze 0,86- dostignet apogeya svoei orbity na rasstoyanii 405615 km ot centra Zemli.

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 21 gradusa, a dolgota dnya na toi zhe shirote - do 9 chasov 45 minut. Vidimyi diametr Solnca uvelichivaetsya do 32,17 minut dugi, a dvizhetsya ono po sozvezdiyu Devy. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 20 oktyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Vodoleya, Ryb, Ovna, Tel'ca, izmenyaya fazu ot 0,9+ do 0,85- i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Vodoleya. 18 oktyabrya pri faze 0,94+ pereidet v sozvezdie Ryb. V etot zhe den' Luna (F= 0,97+) dostignet sozvezdiya Kita, a 19 oktyabrya yarkii lunnyi disk eshe raz pereidet v sozvezdie Ryb pri faze 0,99+. Zdes' nochnoe svetilo primet fazu polnoluniya 20 oktyabrya, nablyudayas' vsyu noch', a 21 oktyabrya vnov' peresechet granicu sozvezdiya Kita. V etot zhe den' pri faze 0,99- yarkii lunnyi disk pereidet v sozvezdie Ovna, gde proidet yuzhnee Urana (F= 0,98-) 21 oktyabrya. V sozvezdie Tel'ca Luna voidet 22 oktyabrya pri faze 0,96-. 23 oktyabrya Luna proidet yuzhnee Pleyad pri faze 0,94-, a 24 oktyabrya budet nahodit'sya bliz Giad i Al'debarana (a takzhe bliz Cerery) pri faze okolo 0,9-. Fazy Luny na dannoe vremya i na budushee.

Iz planet Solnechnoi sistemy: Merkurii viden na fone utrennei zari, 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. Efemeridy Solnca, Luny i planet na kazhdyi den' - http://astropixels.com/.

Iz komet hvostataya strannica P/Churyumov-Gerasimenko (67P) s bleskom okolo 10m peremeshaetsya po sozvezdiyu Bliznecov. Karty putei komet i asteroidov na mesyac imeyutsya v KN na oktyabr', a na drugie periody - v Astronomicheskom kalendare na 2021 god. Podrobnye svedeniya o kometah nedeli i mesyaca (s kartami i prognozami bleska) privodyatsya na http://aerith.net/comet/weekly/current.html , a rezul'taty nablyudenii - na http://195.209.248.207/ .

Sredi asteroidov naibolee yarkoi na dannoi nedele budet Vesta (7,8m) v sozvezdii Vesov, a takzhe Cerera (7,9m) v sozvezdii Tel'ca.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: X Vodoleya 8,1m - 18 oktyabrya, V Bliznecov 8,5m - 19 oktyabrya, S Zmei 9,0m - 20 oktyabrya, Y Perseya 9,0m - 20 oktyabrya, S Bliznecov 8,7m - 22 oktyabrya, Y Drakona 9,1m - 23 oktyabrya.
