Astronomicheskaya nedelya s 8 po 14 aprelya 2024 goda1.04.2024 10:17 | Aleksandr Kozlovskii
Vopros nedeli. V kakom godu (nachinaya s 1961) v nashei strane ne bylo pilotiruemyh kosmicheskih poletov?
Otvety mozhno davat' v kommentariyah k dannoi stranichke.
Na dannoi nedele 8 aprelya asteroid Gerkulina (532) vstupit v protivostoyanie s Solncem, Luna (F= 0,0) okazhetsya v voshodyashem uzle svoei orbity i proizoidet polnoe solnechnoe zatmenie pri vidimosti v Severnoi Amerike. 9 aprelya Luna (F= 0,01+) proidet yuzhnee Merkuriya, a 10 aprelya pri faze 0,06+ - severnee Yupitera. V etot zhe den' Mars proidet v 0,4 severnee Saturna, a Luna (F= 0,07+) - severnee Urana. 11 aprelya proizoidet pokrytie Lunoi (F= 0,11+) Pleyad pri vidimosti v Aravii i Indii, a Merkurii vstupit v nizhnee soedinenie s Solncem. 12 aprelya (den' kosmonavtiki) Luna (F= 0,16+) proidet severnee Giad i Al'debarana. 13 aprelya budet imet' mesto maksimal'naya vostochnaya libraciya Luny po dolgote 7,0 gr., a pri faze 0,31+ Luna proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora. Krome etogo, na vechernem nebe nevooruzhennym glazom mozhno nablyudat' kometu P/Pons-Brooks (12P).
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya ot 42 do 44 gradusov, a dolgota dnya na toi zhe shirote - do 14 chasov 05 minut. Vidimyi diametr Solnca umen'shaetsya ot 31,95 do 31,89 minut dugi, a dvizhetsya ono po sozvezdiyu Ryb. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 8 aprelya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Ryb, Ovna, Tel'ca i Bliznecov, izmenyaya fazu ot 0,01- do 0,42+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Ryb. Zdes' v etot den' Luna primet fazu novoluniya i proizoidet polnoe solnechnoe zatmenie pri vidimosti v Severnoi Amerike. Pereidya na vechernee nebo, molodoi mesyac 9 aprelya proidet yuzhnee Merkuriya pri faze 0,01+, a zatem pereidet v sozvezdie Ovna. Zdes' 10 aprelya Luna (F= 0,06+) budet nahodit'sya bliz Yupitera, Urana i komety P/Pons-Brooks (12P). 11 aprelya pri faze 0,09+ lunnyi serp pereidet v sozvezdie Tel'ca, gde v etot den' proidet yuzhnee Pleyad (pokrytie pri vidimosti v Aravii i Indii). Yuzhnee Luny budet nahodit'sya kometa P/Olbers (13P). 12 aprelya Luna (F= 0,16+) budet nablyudat'sya bliz Giad i Al'debarana. 13 aprelya lunnyi serp (F= 0,3+) vstupit v sozvezdie Bliznecov, gde na sleduyushii den' proidet severnee Vesty. Fazy Luny na dannoe vremya i na budushee.
Iz planet Solnechnoi sistemy: Merkurii mozhno nablyudat' na fone vechernei zari, Venera, Mars i Saturn nahodyatsya na utrennem nebe (luchshaya vidimost' v yuzhnyh shirotah), Neptun ne viden, a Yupiter i Uran nablyudayutsya po vecheram. Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v Astronomicheskih kalendaryah na blizhaishie gody. Efemeridy Solnca, Luny i planet na kazhdyi den' - http://astropixels.com/.
Iz komet hvostataya strannica P/Pons-Brooks (12P) dvizhetsya k yugu po sozvezdiyu Ovna pri vidimosti nevooruzhennym glazom, a kometa PANSTARRS (C/2021 S3) peremeshaetsya k severu po sozvezdiyu Lebedya pri bleske okolo 9m. 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/ .
Sredi asteroidov naibolee yarkoi na dannoi nedele budet Vesta (okolo 8m) v sozvezdii Bliznecov.
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!
