Astronomicheskaya nedelya s 4 po 10 yanvarya 2021 goda1.01.2021 14:02 | Aleksandr Kozlovskii
Na dannoi nedele 4 yanvarya proizoidet pokrytie Lunoi (F= 0,67-) zvezdy nyu Devy (4,0m) pri vidimosti na territorii Rossii (krome Evropeiskoi ee chasti), a 6 yanvarya Luna (F= 0,45-) proidet severnee Spiki. 9 yanvarya Luna (F= 0,16-) okazhetsya v perigee svoei orbity na rasstoyanii 367391 km ot centra Zemli, a 10 yanvarya Merkurii proidet v 1,6 gr. severnee Saturna. V etot zhe den' Luna (F= 0,12-) proidet severnee Antaresa okolo nishodyashego uzla svoei orbity.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy sostavlyaet okolo 12 gradusov, a dolgota dnya na toi zhe shirote uvelichivaetsya do 7 chasov 25 minut. Vidimyi diametr Solnca priderzhivaetsya znacheniya 32,53 minut dugi, a dvizhetsya ono po sozvezdiyu Strel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 6 yanvarya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya L'va, Devy, Vesov, Skorpiona i Zmeenosca, izmenyaya fazu ot 0,75- do 0,05- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii L'va. Eto sozvezdie Luna pokinet 4 yanvarya pri faze 0,69-, vstupiv v sozvezdie Devy. Zdes' lunnyi poludisk 6 yanvarya primet fazu poslednei chetverti, a zatem pri faze 0,45- proidet severnee Spiki. 7 yanvarya staryi mesyac (F= 0,33-) pereidet v sozvezdie Vesov i probudet v nem do 9 yanvarya, kogda dostignet sozvezdiya Skorpiona pri faze 0,16-. V sozvezdie Zmeenosca lunnyi serp voidet v etot zhe den' pri faze 0,13-. Fazy Luny na dannoe vremya i na budushee.
Iz planet Solnechnoi sistemy: Venera vidna na fone utrennei zari, a Mars, Uran i Neptun mozhno nablyudat' vecherom i noch'yu. Yupiter, Saturn i Merkurii nablyudayutsya na fone vechernei zari. Podrobnye efemeridy i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii v AK_2021 na http://www.astronet.ru/db/msg/1704127. Efemeridy Solnca, Luny i planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ .

Karty putei komet i asteroidov na mesyac imeyutsya v KN na yanvar', 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/ .
