Otvety mozhno davat' v kommentariyah k dannoi stranichke.
Na dannoi nedele 1 aprelya Luna (F= 0,14+) proidet bliz Urana, a pri faze 0,16+ bliz rasseyannogo zvezdnogo skopleniya Pleyady (pokrytie pri vidimosti na severe Evropeiskoi chasti Rossii). 2 aprelya Luna (F= 0,27+) prohodit severnee Yupitera i Al'debarana. 3 aprelya budet imet' mesto maksimal'naya yuzhnaya libraciya Luny po shirote 6,8 gr., a pri faze 0,39+ proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora. 5 aprelya Luna (F= 0,58+) proidet bliz Marsa, a takzhe budet imet' mesto maksimal'naya vostochnaya libraciya Luny po dolgote 7,3 gr.. 6 aprelya Merkurii dostignet stoyaniya s perehodom k pryamomu dvizheniyu, a Luna (F= 0,67+) proidet severnee rasseyannogo zvezdnogo skopleniya Yasli (M44).
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 41 gradusa, a dolgota dnya na toi zhe shirote uvelichivaetsya do 13 chasov 30 minut. Vidimyi diametr Solnca umen'shaetsya do 31,96 minut dugi, a dvizhetsya ono po sozvezdiyu Ryb. Dannye o Solnce na tekushee vremya. Efemeridy Solnca na 2025 god
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 5 aprelya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Ovna, Tel'ca, Bliznecov i Raka, izmenyaya fazu ot 0,04+ do 0,69+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Ovna. 1 aprelya pri faze 0,14+ Luna proidet severnee Urana. V etot zhe den' lunnyi serp pereidet v sozvezdie Tel'ca, gde pokroet Pleyady pri faze 0,16+ (vidimost' na severe Evropeiskoi chasti Rossii). 2 aprelya Luna (F= 0,27+) budet nablyudat'sya severnee Yupitera i Al'debarana, a 4 aprelya pri faze 0,39+ lunnyi serp pereidet v sozvezdie Bliznecov. Zdes' 5 aprelya Luna primet fazu pervoi chetverti, a pri faze 0,58+ proidet bliz Marsa, pereidya na sleduyushii den' v sozvezdie Raka uzhe pri faze 0,6+. 6 aprelya lunnyi oval (F= 0,67+) budet nablyudat'sya bliz rasseyannogo zvezdnogo skopleniya Yasli (M44). 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 Del'fina. 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/ .
