Astronomicheskaya nedelya s 22 po 28 yanvarya 2018 goda6.01.2018 10:10 | Aleksandr Kozlovskii
Na dannoi nedele Luna proidet bliz Urana okolo fazy pervoi chetverti, asteroid Partenopa (10m) proidet protivostoyanie s Solncem, a 27 yanvarya proizoidet pokrytie Lunoi (F= 0,77+) zvezd skopleniya Giady i Al'debarana pri vidimosti v Sibiri i na Dal'nem Vostoke strany.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 16 gradusov, a dolgota dnya na toi zhe shirote - do 8 chasov 20 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shitsya do 32,48 minut dugi, a dvizhetsya ono po sozvezdiyu Kozeroga. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 24 yanvarya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Vodoleya, Ryb, Ovna i Tel'ca, izmenyaya fazu ot 0,,2+ do 0,9+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Vodoleya, podnimayas' vse vyshe i nablyudayas' na vechernem nebe vysoko nad gorizontom. 23 yanvarya Luna posetit sozvezdie Kita, a na sleduyushii den' proidet yuzhnee Urana pri faze 0,4+. 24 yanvarya nochnoe svetilo primet fazu pervoi chetverti, a 25 yanvarya lunnyi poludisk vnov' posetit sozvezdie Kita, chtoby na sleduyushii den' pereiti v sozvezdie Ovna pri faze blizkoi k 0,6+. Zaderzhavshis' nenadolgo v etom sozvezdii, rastushii oval 26 yanvarya peresechet granicu s sozvezdiem Tel'ca i ustremitsya k pokrytiyu zvezd skopleniya Giady i Al'debarana, kotoroe proizoidet 27 yanvarya pri faze 0,77+. Na sleduyushii den' yarkaya Luna posetit sozvezdie Oriona pri faze okolo 0,9+, a 29 yanvarya pereidet v sozvezdie Bliznecov, proidya tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora. Faza Luny na tekushii moment. Fazy Luny na budushee.
