Astronomicheskaya nedelya s 18 po 24 marta 2019 goda Astronomicheskaya nedelya s 18 po 24 marta 2019 goda
8.03.2019 19:31 | Aleksandr Kozlovskii

Na dannoi nedele 18 marta dolgoperiodicheskaya peremennaya zvezda SS Devy dostignet maksimuma bleska (6m), 19 marta Luna (F= 0,94+) proidet severnee Regula okolo perigeya svoei orbity na rasstoyanii 359378 km ot centra Zemli, 20 marta nastupit vesennee ravnodenstvie, 21 marta dolgoperiodicheskaya peremennaya zvezda RR Skorpiona dostignet maksimuma bleska (5m), a 25 marta Merkurii proidet v 2,4 gr. severnee Neptuna. Krome etogo, kometa Iwamoto (C/2018 Y1) yavlyaetsya nezahodyashim svetilom severnee shiroty Moskvy.

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 35 gradusov, a dolgota dnya na toi zhe shirote - do 12 chasov 25 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shaetsya do 32,08 minut dugi, a dvizhetsya ono po sozvezdiyu Ryb. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 21 marta. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Raka, L'va, Devy i Vesov, izmenyaya fazu ot 0,85+ do 1,0, a zatem do 0,80- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Raka. 18 marta yarkii lunnyi oval (F= 0,88+) pereidet v sozvezdie L'va i ustremitsya k Regulu, severnee kotorogo proidet na sleduyushii den' pri faze 0,94+ i bliz perigeya svoei orbity (19 marta). V sozvezdii L'va Luna probudet do 20 marta, kogda pri faze 0,99+ pereidet v sozvezdie Devy. Zdes' lunnyi oval 21 marta primet fazu polnoluniya, a 22 marta proidet severnee Spiki pri faze 0,97-. 23 marta pri faze 0,92- Luna pereidet v sozvezdie Vesov, gde probudet do 25 marta, umen'shiv fazu do 0,77-. Fazy Luny na dannoe vremya i na budushee.

Podrobnye efemeridy i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii AK_2019 na http://www.astronet.ru/db/msg/1364101 . Efemeridy planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ephemeris/ephemeris.html .

Iz komet hvostataya strannica P/Wirtanen (46P) dvizhetsya po sozvezdiyu Malogo L'va s bleskom slabee 11m. Kometa Iwamoto (C/2018 Y1) peremeshaetsya po sozvezdiyu Perseya s bleskom slabee 9m, yavlyayas' nezahodyashim svetilom v severnyh raionah strany. Karty putei komet i asteroidov na mesyac imeyutsya v KN na mart, a na drugie periody - v Astronomicheskom kalendare na 2019 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 na dannoi nedele budut: Vesta (7,9m) v sozvezdii Vodoleya i Pallada (7,9m) v sozvezdii Volopasa.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: SS Devy 6,8m - 18 marta, V L'va 9,1m - 21 marta, RR Skorpiona 5,9m - 21 marta.

Nekotorye blizkie pary svetil: Luna - Regul, Luna - Spika, Mars - Uran, Yupiter - Antares, Saturn - omikron Strel'ca, Uran - omikron Ryb, Neptun - lyambda Vodoleya, kometa P/Wirtanen (46P) - kometa P/Stephan-Oterma (38P), kometa Iwamoto (C/2018 Y1) - M36.

Nedel'nyi obzor ot zhurnala "Skai end Teleskop", no nuzhno uchityvat', chto kartinki dayutsya dlya 40 severnoi shiroty, a polozhenie Luny i planet na 7 chasov pozdnee otnositel'no moskovskogo vremeni!

Yasnogo neba i uspeshnyh nablyudenii!

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 18 marta - v 1988 godu, 19 marta - v 1113 godu, 20 marta - v 2015 godu, 21 marta - v 1159 godu, 22 marta - v 0201 godu, 23 marta - v 1308 godu, 24 marta - v 1811 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 19 marta (7 zatmenii), a men'she vsego - 22 marta (2 zatmeniya). Your Guide to the 2017 Total Solar Eclipse
