Astronomicheskaya nedelya s 15 po 21 yanvarya 2018 goda5.01.2018 19:10 | Aleksandr Kozlovskii
Na dannoi nedele Luna (F= 0,04-) proidet bliz Merkuriya i Saturna (15 yanvarya), V etot zhe den' Luna (F= 0,04-) okazhetsya v apogee svoei orbity na rasstoyanii 406460 km ot centra Zemli (samoe bol'shoe udalenie Luny ot Zemli za 2018 god) pri maksimal'nom sklonenii k yugu ot nebesnogo ekvatora,. 17 yanvarya Luna v faze novoluniya proidet bliz Venery (ne vidno), a na sleduyushii den' dolgoperiodicheskaya peremennaya zvezda V Gonchih Psov dostignet maksimuma bleska (6m), 18 yanvarya Luna (F= 0,02+) proidet nishodyashii uzel svoei orbity, a 20 yanvarya rastushii serp (F= 0,13+) sblizitsya s Neptunom.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 14 gradusov, a dolgota dnya na toi zhe shirote - do 8 chasov 00 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shitsya do 32,50 minut dugi, a dvizhetsya ono po sozvezdiyu Strel'ca, 20 yanvarya perehodya v sozvezdie Kozeroga. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 17 yanvarya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Strel'ca, Kozeroga i Vodoleya, izmenyaya fazu ot 0,1- do 0, a zatem do 0,,2+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Strel'ca, gde proidet severnee Merkuriya i Saturna utrom 15 yanvarya (bliz maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora i apogeya svoei orbity). 17 yanvarya Luna primet fazu novoluniya u granicy sozvezdii Strel'ca i Kozeroga, i pereidet na vechernee nebo bliz Venery (ne vidno). V sozvezdie Kozeroga Luna budet uvelichivat' fazu do 0,05+, poka ne dostignet granicy s sozvezdiem Vodoleya, kuda pereidet 19 yanvarya, a na sleduyushii den' sblizitsya s Neptunom pri faze 0,13+. Pokrytiya planety ne proizoidet, t.k. seriya pokrytii Neptuna zakonchilas', a sleduyushaya seriya nachnetsya v 2023 godu. Faza Luny na tekushii moment. Fazy Luny na budushee.
