Astronomicheskaya nedelya s 7 po 13 maya 2018 goda4.05.2018 17:17 | Aleksandr Kozlovskii
Na dannoi nedele Luna (F= 0,56-) dostignet nishodyashego uzla svoei orbity (7 maya), a 8 maya asteroid Evnomiya okazhetsya v protivostoyanii s Solncem. Na sleduyushii den' protivostoyaniya s Solncem dostignet Yupiter, a dolgoperiodicheskie peremennye zvezdy RS Lebedya i R Devy - maksimuma bleska (6m). 10 maya Luna (F= 0,28-) proidet bliz Neptuna, a 13 maya Merkurii proidet v 2,2 gr. yuzhnee Urana. V etot zhe den' Luna (F= 0,05-) sblizitsya s Merkuriem i Uranom. Poyavilas' Novaya zvezda v sozvezdii Perseya (6m). Udobna dlya nablyudenii v srednih i yuzhnyh shirotah strany. Podrobnee na Astroforume.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 53 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 10 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shitsya do 31,65 minut dugi, a dvizhetsya ono po sozvezdiyu Ovna. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 08 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Kozeroga, Vodoleya i Ryb, izmenyaya fazu ot 0,6- do 0 i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Kozeroga. Zdes' Luna 8 maya primet fazu poslednei chetverti, nablyudayas' v predrassvetnye chasy nad vostochnym gorizontom (bliz apogeya svoei orbity). V etot zhe den' uzhe lunnyi serp (F= 0,43-) peresechet granicu sozvezdiya Vodoleya, gde proidet bliz Neptuna pri faze 0,28- 10 maya. Na sleduyushii den' tayushii serp (F= 0,2-) pereidet v sozvezdie Ryb, a 12 maya provedet v sozvezdii Kita, umen'shiv fazu do 0,1-. 13 maya stareyushii mesyac provedet v sozvezdii Ryb, proidya v etot zhe den' yuzhnee Merkuriya i Urana. Faza Luny na tekushii moment. Fazy Luny na budushee.
Iz planet Solnechnoi sistemy: Venera yarko siyaet na fone vechernei zari. Merkurii viden v luchah voshodyashego Solnca, no tol'ko v yuzhnyh raionah strany. Mars i Saturn vidny v utrennie chasy, Yupiter nablyudaetsya noch'yu i utrom, a Uran i Neptun mozhno naiti v utrennih sumerkah.

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 07 maya - v 1529 godu, 08 maya - v 1510 godu, 09 maya - v 1929 godu, 10 maya - v 1575 godu, 11 maya - v 1687 godu, 12 maya - v 1706 godu, 13 maya - v 1752 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 10 i 13 maya (po 7 zatmenii!), a men'she vsego 7 maya (2 zatmeniya). Your Guide to the 2017 Total Solar Eclipse
