Astronomicheskaya nedelya s 14 po 20 maya 2018 goda Astronomicheskaya nedelya s 14 po 20 maya 2018 goda
11.05.2018 19:31 | Aleksandr Kozlovskii

Na dannoi nedele dolgoperiodicheskie peremennye zvezdy R Lebedya (6,5m) i R Treugol'nika (5m) dostignut maksimuma bleska, a Venera proidet perigelii svoei orbity. 16 maya proizoidet pokrytie Lunoi (F= 0,01+) Al'debarana pri vidimosti v severnyh shirotah, a 17 maya Luna (F= 0,05+) proidet bliz Venery okolo perigeya svoei orbity na rasstoyanii 363772 km ot centra Zemli. 18 maya Luna (F= 0,13+) dostignet maksimal'nogo skloneniya k severu ot nebesnogo ekvatora, a 20 maya pri faze 0,31+ proidet bliz zvezdnogo skopleniya Yasli (M44) okolo voshodyashego uzla svoei orbity. Novaya zvezda v sozvezdii Perseya slabeet. Krome etogo, nachinaetsya sezon serebristyh oblakov, kotorye poyavlyayutsya na fone vechernih i utrennih sumerek. Esli zhe vechernie sumerki slivayutsya s utrennimi, to serebristye oblaka mogut nablyudat'sya v techenie nochi.

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 54 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 35 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shitsya do 31,61 minut dugi, a dvizhetsya ono po sozvezdiyu Tel'ca. 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 Ryb, Ovna, Tel'ca, Bliznecov i Raka, izmenyaya fazu ot 0 do 0,4+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii do serediny nedeli (a zatem umen'shaya). Nachalo nedeli nochnoe svetilo provedet v sozvezdii Ryb. 14 maya Luna vnov' posetit sozvezdie Kita i v etot zhe den' pereidet v sozvezdie Ovna, chtoby 15 maya pereiti v sozvezdie Tel'ca. Zdes' v etot den' nastupit novolunie. Poyavivshis' na sleduyushii den' na vechernem nebe, molodoi mesyac pokroet pri faze 0,01+ zvezdu Al'debaran pri vidimosti v severnyh shirotah, a 17 maya proidet yuzhnee Venery (F= 0,05+). 18 maya serp Luny (F= 0,1+) posetit sozvezdie Oriona, a zatem pereidet v sozvezdie Bliznecov. Zdes' rastushii serp proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora bliz perigeya svoei orbity, nablyudayas' vysoko na vechernem nebe. V sozvezdie Raka lunnyi serp vstupit 19 maya pri faze 0,25+, a 20 maya proidet yuzhnee zvezdnogo skopleniya Yasli - M44 (bliz voshodyashego uzla svoei orbity). 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. Podrobnye efemeridy i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii AK_2018 na http://www.astronet.ru/db/msg/1364103 . Efemeridy planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ephemeris/ephemeris.html .

Iz komet hvostataya strannica C/2016 R2 ( PanSTARRS ) vidna v sozvezdii Voznichego, imeya blesk slabee 12m. Kometa PANSTARRS (C/2016 M1) dvizhetsya po sozvezdiyu Strel'ca pri bleske okolo 10m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na mai, 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 (8,5m) v sozvezdii Raka i L'va i Vesta (6,0m) v sozvezdii Strel'ca. Vestu pri blagopriyatnyh usloviyah mozhno naiti nevooruzhennym glazom.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: X Kita 8,8m - 14 maya, R Lebedya 7,5m - 15 maya, RR Perseya 9,2m - 16 maya, R Treugol'nika 6,2m - 16 maya, S Maloi Medvedicy 8,4m - 20 maya.

Nekotorye blizkie pary svetil: Luna - Uran, Luna - Merkurii, Luna - Al'debaran, Luna - Venera, Luna - Yasli (M44), Merkurii - Uran, Mars - Saturn, Saturn - Vesta, Yupiter - al'fa Vesov, Uran - omikron Ryb, Neptun - lyambda Vodoleya.

Yasnogo neba i uspeshnyh nablyudenii!

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 14 maya - v 1771 godu, 15 maya - v 0831 godu, 16 maya - v 1417 godu, 17 maya - v 1882 godu, 18 maya - v 1901 godu, 19 maya - v 1928 godu, 20 maya - v 1947 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 19 maya (7 zatmenii!), a men'she vsego 18 maya (2 zatmeniya). Your Guide to the 2017 Total Solar Eclipse
