Otvety mozhno davat' v kommentariyah k dannoi stranichke.
Na dannoi nedele 21 aprelya budet imet' mesto maksimal'naya zapadnaya libraciya Luny po dolgote 7,6, a Merkurii dostignet maksimal'noi zapadnoi (utrennei) elongacii 27 gradusov. 22 aprelya nastupit maksimum deistviya meteornogo potoka Liridy (ZHR= 18), a 24 aprelya Venera proidet v 4 gradusah k severu ot Saturna. 25 aprelya Luna (F= 0,11-) okazhetsya v voshodyashem uzle svoei orbity bliz Saturna i Venery, pri faze 0,09- budet nahodit'sya bliz Neptuna, a pri faze 0,05- bliz Merkuriya. 27 aprelya Luna (F= 0,0) dostignet perigeya svoei orbity na rasstoyanii 357119 km ot centra Zemli.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 48 gradusov, a dolgota dnya na toi zhe shirote uvelichivaetsya do 15 chasov 05 minut. Vidimyi diametr Solnca umen'shaetsya do 31,77 minut dugi, a dvizhetsya ono po sozvezdiyu Ovna. Dannye o Solnce na tekushee vremya. Efemeridy Solnca na 2025 god
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 27 aprelya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Kozeroga, Vodoleya, Ryb i Ovna, izmenyaya fazu ot 0,51- do 0,0 i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Kozeroga. Zdes' 21 aprelya Luna primet fazu poslednei chetverti. 22 aprelya lunnyi serp pri faze 0,3- pereidet v sozvezdie Vodoleya, a 24 aprelya - v sozvezdie Ryb uzhe pri faze 0,12-. Utrom 25 aprelya Luna budet nablyudat'sya bliz Merkuriya, Venery, Saturna i Neptuna pri faze okolo 0,1-. 27 aprelya Luna (F= 0,01-) pereidet v sozvezdie Ovna, gde v etot zhe den' primet fazu novoluniya. Fazy Luny na dannoe vremya i na budushee. Efemeridy Luny na 2025 god
Planety Solnechnoi sistemy. Merkurii, Venera, Saturn i Neptun nahodyatsya na utrennem nebe, a Mars, Yupiter i Uran - na vechernem nebe. Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v Astronomicheskom kalendare na 2025 god i Astronomicheskih kalendaryah na blizhaishie gody.
Komety. Hvostataya strannica Tsuchinshan-ATLAS (C/2023 A3) pri bleske slabee 12m dvizhetsya po sozvezdiyu Lisichki. Karty putei komet i asteroidov na mesyac imeyutsya v Kalendare nablyudatelya na blizhaishie mesyacy, a na drugie periody - v Astronomicheskih kalendaryah na blizhaishie gody. 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/ .
Asteroidy. Naibolee yarkoi na dannoi nedele budet Vesta (okolo 6m) v sozvezdii Vesov.
