Astronomicheskaya nedelya s 15 po 21 yanvarya 2018 goda Astronomicheskaya nedelya s 15 po 21 yanvarya 2018 goda
12.01.2018 18:10 | 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.

Iz planet Solnechnoi sistemy: Venera ne vidna, Merkurii i Saturn nablyudayutsya na fone utrennei zari. Mars i Yupiter vidny v utrennie chasy, a Uran i Neptun mozhno naiti v binokl' ili teleskop na vechernem i nochnom nebe. Podrobnye efemeridy planet i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii http://www.astronet.ru/db/msg/1364103 . Efemeridy planety na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ephemeris/ephemeris.html

Iz komet hvostataya strannica C/2017 O1 (ASASSN1) pri bleske slabee 11m dvizhetsya po sozvezdiyu Cefeya. Kometa Heinze (C/2017 T1) dvizhetsya po sozvezdiyu Yashericy s bleskom okolo 11m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na yanvar', a na drugie periody - v Astronomicheskom kalendare na 2018 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/ .

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: Z Pegasa 8,4m - 15 yanvarya, X Severnoi Korony 9,1m - 15 yanvarya, RS Devy 8,1m - 16 yanvarya, V Gonchih Psov 6,8m - 18 yanvarya, S Malogo L'va 8,6m - 19 yanvarya.

Iz osnovnyh meteornyh potokov naibolee aktivny Kvadrantidy .

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 15 yanvarya - v 1572 godu, 16 yanvarya - v 0093 godu, 17 yanvarya - v 1703 godu, 18 yanvarya - v 1749 godu, 19 yanvarya - v 1768 godu, 20 yanvarya - v 0288 godu, 21 yanvarya - v 1395 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 18 yanvarya (6 zatmenii), a men'she vsego - 16 i 20 yanvarya (po 1 zatmeniyu).
