Astronomicheskaya nedelya s 26 iyunya po 2 iyulya 2023 goda23.06.2023 10:53 | Aleksandr Kozlovskii
Na dannoi nedele 27 iyunya nastupit maksimum deistviya meteornogo potoka Iyun'skie Bootidy (potok peremennyi, ZHR= 0 - 100), a Luna (F= 0,65+) proidet severnee Spiki. 28 iyunya Luna (F= 0,71+) okazhetsya v nishodyashem uzle svoei orbity, a 1 iyulya Merkurii dostignet verhnego soedineniya s Solncem. V etot zhe den' Luna (F= 0,94+) proidet severnee Antaresa, a Neptun dostignet stoyaniya s perehodom k popyatnomu dvizheniyu. Krome etogo, ves' mesyac imeetsya vozmozhnost' poyavleniya serebristyh oblakov na fone vechernei i utrennei zari.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy priderzhivaetsya znacheniya 57 gradusov, a dolgota dnya na toi zhe shirote umen'shitsya do 17 chasov 25 minut. Vidimyi diametr Solnca umen'shaetsya ot 31,47 do 31,46 minut dugi, a dvizhetsya ono po sozvezdiyu Bliznecov. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 26 iyunya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Devy, Vesov, Skorpiona, Zmeenosca i Strel'ca, izmenyaya fazu ot 0,47+ do 0,99+ i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Devy. Zdes' nochnoe svetilo primet fazu pervoi chetverti 26 iyunya (bliz Spiki), a 29 iyunya pri faze 0,76+ pereidet v sozvezdie Vesov. 30 iyunya pri faze 0,89+ yarkaya Luna dostignet sozvezdiya Skorpiona, gde i zakonchit put' po iyun'skomu nebu pri faze 0,91+ bliz Antaresa. Zatem nochnoe svetilo pereidet v sozvezdie Zmeenosca. 2 iyulya Luna (F= 0,98+) pereidet v sozvezdie Strel'ca. V etom sozvezdii Luna primet fazu polnoluniya 3 iyulya. Fazy Luny na dannoe vremya i na budushee.

Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v Astronomicheskom kalendare na 2023 god. Efemeridy Solnca, Luny i planet na kazhdyi den' - http://astropixels.com/.

Karty putei komet i asteroidov na mesyac imeyutsya v KN na iyun', KN na iyul', a na drugie periody - v Astronomicheskom kalendare na 2023 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/ .
