Astronomicheskaya nedelya s 16 po 22 dekabrya 2019 goda Astronomicheskaya nedelya s 16 po 22 dekabrya 2019 goda
25.11.2019 5:40 | Aleksandr Kozlovskii

Na dannoi nedele 16 dekabrya Merkurii proidet v 5 gradusah severnee Antaresa, a 17 dekabrya Luna (F= 0,71-) proidet severnee Regula. 18 dekabrya Luna (F= 0,54-) okazhetsya v perigee svoei orbity na rasstoyanii 370259 km ot centra Zemli, a 19 dekabrya proizoidet pokrytie Lunoi (F= 0,52-) zvezdy nyu Devy (4,0m) pri vidimosti na Evropeiskoi chasti Rossii i v Sibiri. V etot zhe den' dolgoperiodicheskaya peremennaya zvezda R Devy dostignet maksimuma bleska (6m), a 20 dekabrya Luna (F= 0,3-) proidet bliz Spiki. 22 dekabrya nastupit maksimum deistviya meteornogo potoka Ursidy (ZHR= 10) iz sozvezdiya Maloi Medvedicy, a Solnce v 4 chasa 19 minut po vsemirnomu vremeni dostignet nizshei tochki ekliptiki i proidet tochku zimnego solncestoyaniya v svoem godichnom puti po nebesnoi sfere.

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy priderzhivaetsya znacheniya 11 gradusov, a dolgota dnya na toi zhe shirote - 7 chasov 00 minut. Vidimyi diametr Solnca uvelichivaetsya do 32,52 minut dugi, a dvizhetsya ono po sozvezdiyu Zmeenosca. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 19 dekabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Raka, L'va, Devy i Vesov, izmenyaya fazu ot 0,8- do 0,1- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Raka. Ustremivshis' k sozvezdiyu L'va, Luna voidet v nego 16 dekabrya pri faze 0,8-. V sozvezdii L'va 17 dekabrya lunnyi oval proidet severnee Regula pri faze 0,71-. 18 dekabrya (F= 0,54-) lunnyi poludisk pereidet v sozvezdie Devy, dostignuv pri etom perigeya svoei orbity na rasstoyanii 370259 km ot centra Zemli. Zdes' 19 dekabrya Luna primet fazu poslednei chetverti i sovershit puteshestvie po sozvezdiyu Devy, 20 dekabrya pri faze 0,3- proidya severnee Spiki. Okolo polunochi 22 dekabrya lunnyi serp (F= 0,2-) pereidet v sozvezdie Vesov. Fazy Luny na dannoe vremya i na budushee.

Iz planet Solnechnoi sistemy: Merkurii i Mars nablyudayutsya po utram, a Venera, Yupiter i Saturn nahodyatsya na vechernem nebe. Uran i Neptun mozhno nablyudat' bol'shuyu chast' nochi. Podrobnye efemeridy i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii AK_2019 na http://www.astronet.ru/db/msg/1364101 . Efemeridy planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ephemeris/ephemeris.html .

Iz komet hvostataya strannica PANSTARRS (C/2017 T2) dvizhetsya po sozvezdiyam Perseya i Zhirafa s bleskom okolo 10m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na dekabr', a na drugie periody - v Astronomicheskom kalendare na 2020 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 (7,1m) v sozvezdii Kita.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: S Kompasa 9,0m - 16 dekabrya, RS Devy 8,1m - 16 dekabrya, R Devy 6,9m - 19 dekabrya, V L'va 9,1m - 20 dekabrya.

Nekotorye blizkie pary svetil: Luna - Yasli (M44), Luna - Regul, Luna - Spika, Luna - Mars, Merkurii - Antares, Mars - al'fa Vesov, Yupiter - Antares, Venera - Saturn, Saturn - omikron Strel'ca, Uran - al'fa Ovna, Neptun - fi Vodoleya, kometa C/2018 N2 ( ASASSN ) - M31.

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 16 dekabrya - v 1694 godu, 17 dekabrya - 1713 godu, 18 dekabrya - v 1191 godu, 19 dekabrya - v 1340 godu, 20 dekabrya - v 0819 godu, 21 dekabrya - v 1843 godu, 22 dekabrya - v 1889 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 22 dekabrya (7 zatmenii), a men'she vsego 20 i 21 dekabrya (po 2 zatmeniya). Your Guide to the 2017 Total Solar Eclipse
