Astronomicheskaya nedelya s 22 po 28 iyulya 2019 goda19.07.2019 6:31 | Aleksandr Kozlovskii
Na dannoi nedele 24 iyulya dolgoperiodicheskie peremennye zvezdy T Bol'shoi Medvedicy (6,5m) i V Gonchih Psov (5,5m) dostignut maksimuma bleska. 25 iyulya Merkurii proidet v 5,6 gr. yuzhnee Venery, a Luna (F= 0,47-) - yuzhnee Urana. 26 iyulya dolgoperiodicheskaya peremennaya zvezda R Devy dostignet maksimuma bleska (5,5m), a 28 iyulya Luna (F= 0,2-) proidet severnee Al'debarana. Krome etogo, prodolzhaetsya period poyavleniya serebristyh oblakov na fone sumerechnogo segmenta v srednih shirotah strany.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 53 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 15 minut. Vidimyi diametr Solnca uvelichivaetsya do 31,50 minut dugi, a dvizhetsya ono po sozvezdiyu Raka. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 25 iyulya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Vodoleya, Ryb, Ovna i Tel'ca, izmenyaya fazu ot 0,8- do 0,15- i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Vodoleya bliz Neptuna. 22 iyulya Luna pereidet v sozvezdie Ryb pri faze 0,76-. Prodolzhaya umen'shat' fazu, nochnoe svetilo v etot zhe den' pereidet v sozvezdie Kita pri faze 0,71-, a 24 iyulya (F= 0,6-) vnov' pereidet v sozvezdie Ryb, gde 25 iyulya primet fazu poslednei chetverti. Pri etoi faze lunnyi poludisk eshe raz pereidet v sozvezdie Kita, proidya 25 iyulya yuzhnee Urana. V etot zhe den' Luna dostignet sozvezdiya Ovna, sniziv fazu do 0,43-, a 26 iyulya vtoroi raz v iyule posetit sozvezdie Tel'ca, peresekaya ego granicu pri faze 0,34-. Zdes' stareyushii mesyac 28 iyulya proidet severnee Al'debarana (F= 0,2-). Fazy Luny na dannoe vremya i na budushee.

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 22 iyulya - v 2009 godu, 23 iyulya - 1153 godu, 24 iyulya - v 1702 godu, 25 iyulya - v 1786 godu, 26 iyulya - v 1348 godu, 27 iyulya - v 1832 godu, 28 iyulya - v 1851 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 23 i 27 iyulya (po 7 zatmenii), a men'she vsego - 28 iyulya (3 zatmeniya). Your Guide to the 2017 Total Solar Eclipse

Dlya vizual'nyh nablyudenii Plutona neobhodim teleskop s diametrom ob'ektiva ot 250 mm (v periody nailuchshei vidimosti) i prozrachnoe nebo, a ideal'noe mesto dlya ego nablyudenii - v ekvatorial'noi oblasti Zemli.
