Astronomicheskaya nedelya s 23 po 29 oktyabrya 2017 goda25.09.2017 19:10 | Aleksandr Kozlovskii
Na dannoi nedele dolgoperiodicheskaya peremennaya zvezda hi Lebedya dostignet maksimuma bleska (4m), Luna (F= 0,2+) proidet bliz Saturna, a asteroid (2) Pallada (8,2m) vstupit v protivostoyanie s Solncem (24 oktyabrya). 25 oktyabrya Luna (F= 0,25+) okazhetsya v apogee svoei orbity na rasstoyanii ot centra Zemli 405150 km pri maksimal'nom sklonenii k yugu. V seredine nedeli Yupiter vstupit v soedinenie s Solncem, a 27 oktyabrya kometa P/Machholz (96P) prohodit perigelii orbity (0,124 a.e). V konce nedeli Luna (F= 0,63+) proidet nishodyashii uzel svoei orbity.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya k koncu nedeli do 20 gradusov, a dolgota dnya na toi zhe shirote - do 9 chasov 25 minut. Vidimyi diametr Solnca za opisyvaemyi period uvelichitsya do 32,20 minut dugi, a dvizhetsya ono po sozvezdiyu Devy. Tekushie dannye o Solnce i vid ego poverhnosti na dannoe vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 27 oktyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Skorpiona, Zmeenosca, Strel'ca, Kozeroga i Vodoleya, izmenyaya fazu ot 0,1+ do 0,7+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Skorpiona. 23 oktyabrya molodoi mesyac pereidet v sozvezdie Zmeenosca pri faze 0,1+. Dostignuv 24 oktyabrya soedineniya s Saturnom (F= 0,2+) Luna proidet severnee okol'covannoi planety i v etot zhe den' vstupit v sozvezdie Strel'ca. Zdes' rastushii serp budet nahodit'sya do 27 oktyabrya, nablyudayas' nizko nad gorizontom, nahodyas' bliz apogeya orbity i maksimal'nogo yuzhnogo skloneniya. V sozvezdie Kozeroga Luna pereidet pri faze 0,44+ i primet zdes' fazu pervoi chetverti 27 oktyabrya. Granicu s sozvezdiem Vodoleya lunnyi oval (F= 0,67+) peresechet vecherom 29 oktyabrya. Faza Luny na tekushii moment. Fazy Luny na budushee.
Iz planet Solnechnoi sistemy: Merkurii ne viden, Venera i Mars nablyudayutsya v utrennih sumerkah (Venera vidna takzhe i dnem). Yupiter ne viden, Saturn mozhno nablyudat' v vechernie chasy, a Uran i Neptun vidny vsyu noch'. Podrobnye efemeridy planet i karty dvizheniya dayutsya v pechatnoi versii Astronomicheskogo kalendarya na 2017 god .

Iz komet hvostataya strannica C/2017 O1 (ASASSN1) pri bleske yarche 9m dvizhetsya po sozvezdiyu Zhirafa. P/Machholz (96P) mozhet byt' naidena v yuzhnyh shirotah, no nahoditsya ona blizko k Solncu. Karty putei komet i asteroidov na mesyac imeyutsya v KN na oktyabr', a na drugie periody - v Astronomicheskom kalendare na 2017 god.

Nedel'nyi obzor ot zhurnala "Skai end Teleskop", no nuzhno uchityvat', chto kartinki dayutsya dlya 40 severnoi shiroty, a polozhenie Luny i planet na 7 chasov pozdnee otnositel'no moskovskogo vremeni!
Yasnogo neba i uspeshnyh nablyudenii!
Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 23 oktyabrya - v 1976 godu, 24 oktyabrya - v 1995 godu, 25 oktyabrya - v 1650 godu, 26 oktyabrya - v 1753 godu, 27 oktyabrya - v 1780 godu, 28 oktyabrya - v 1799 godu, 29 oktyabrya - v 1818 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 23 oktyabrya (7 zatmenii!), a men'she vsego 25 i 26 oktyabrya (po 2 zatmeniya).

Merkurii. Planeta peremeshaetsya v odnom napravlenii s Solncem po sozvezdiyu Vesov. Merkurii nahoditsya na vechernem nebe (pri elongacii 12 gradusov k koncu nedeli), no nablyudat' ego v srednih shirotah strany ne predstavlyaetsya vozmozhnym.
