Astronomicheskaya nedelya s 12 po 18 marta 2018 goda Astronomicheskaya nedelya s 12 po 18 marta 2018 goda
16.02.2018 18:01 | Aleksandr Kozlovskii

Na dannoi nedele Luna (F= 0,1-) proidet nishodyashii uzel svoei orbity, a Merkurii dostignet maksimal'noi vechernei (vostochnoi) elongacii 18 gradusov (15 marta). Prinyav fazu novoluniya 17 marta, Luna vyidet na vechernee nebo i v konce nedeli tonkii serp molodogo mesyaca budet krasovat'sya okolo Merkuriya i Venery. Eto budet samyi zrelishnyi vecher marta!

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 33 gradusov, a dolgota dnya na toi zhe shirote - do 12 chasov 00 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shitsya do 32,14 minut dugi, a dvizhetsya ono po sozvezdiyu Ryb. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 17 marta. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Strel'ca, Kozeroga, Vodoleya i Ryb, izmenyaya fazu ot 0,3- do 0 i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Strel'ca (bliz maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora i apogeya svoei orbity). V konce dnya 12 marta serp Luny (F= 0,2-) pokinet sozvezdie Strel'ca, pereidya v sozvezdie Kozeroga. Zdes' Luna 14 marta proidet nishodyashii uzel svoei orbity. 15 marta lunnyi serp umen'shit fazu do 0,05- i peresechet granicu sozvezdiya Vodoleya, gde primet fazu novoluniya 17 marta (bliz granicy s sozvezdiem Ryb). Pereidya v sozvezdie Ryb, molodoi mesyac (F= 0,02+) poyavitsya na vechernem nebe bliz Venery 18 marta. Faza Luny na tekushii moment. Fazy Luny na budushee.

Iz planet Solnechnoi sistemy: Merkurii i Veneru mozhno naiti na fone vechernei zari, Mars, Yupiter i Saturn vidny v utrennie chasy, Uran mozhno naiti v binokl' ili teleskop na vechernem nebe, a Neptun pereshel na utrennee nebo, no ego vidimost' nachnetsya tol'ko v aprele. Podrobnye efemeridy planet i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii AK_2018 na 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/2016 R2 ( PanSTARRS ) vidna v sozvezdii Perseya , imeya blesk okolo 11m. Kometa PANSTARRS (C/2016 M1) dvizhetsya po sozvezdiyu Orla pri bleske okolo 12m. Nabiraet yarkost' kometa 185P/Petriew (11m). Karty putei komet i asteroidov na mesyac imeyutsya v KN na mart, 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/ .

Sredi asteroidov naibolee yarkimi i udobnymi dlya nablyudenii na dannoi nedele budut: Cerera (7,7m) v sozvezdii Raka i Vesta (7,3m) v sozvezdii Zmeenosca i Strel'ca.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: RT Centavra 9,0m - 12 marta, S Mikroskopa 9,0m - 15 marta, V Pegasa 8,7m - 17 marta, W Voznichego 9,2m - 18 marta.
