Astronomicheskaya nedelya s 4 po 10 sentyabrya 2017 goda25.08.2017 15:31 | Aleksandr Kozlovskii
Na dannoi nedele (ves'ma nasyshennoi yavleniyami) 4 sentyabrya Merkurii dostignet stoyaniya s perehodom k pryamomu dvizheniyu (bliz Marsa), a Luna (F= 0,97+) okazhetsya v nishodyashem uzle orbity. Na sleduyushii den' Neptun proidet protivostoyanie s Solncem, a Mars - v 0,7 gr. severnee Regula. 6 sentyabrya proizoidet pokrytie Lunoi (F= 1,0) planety Neptun pri vidimosti v Yuzhnoi Amerike i Antarktide, a Luna dostignet maksimal'noi zapadnoi libracii. Na sleduyushii den' asteroid (89) Yuliya (9,0m) proidet protivostoyanie s Solncem, a 8 sentyabrya dolgoperiodicheskaya peremennaya zvezda S Bol'shoi Medvedicy dostignet maksimal'nogo bleska 7m. 9 sentyabrya mozhno budet nablyudat' maksimum deistviya meteornogo potoka Sentyabr'skie epsilon-Perseidy (ZHR= 5), a Luna proidet bliz Urana pri faze okolo 0,9-. V noch' s 9 na 10 sentyabrya pokrytie zvezdy sigma 1 Tel'ca (5,1m) asteroidom 6925 Susumu pri vidimosti na Evropeiskoi chasti Rossii(!!), a v konce nedeli Merkurii proidet v 0,7 gr. yuzhnee Regula. Krome etogo, eshe imeetsya vozmozhnost' nablyudeniya okolozemnogo asteroida Florence (3122), kotoryi bystro podnimaetsya na sever po sozvezdiyam Lisichki i Lebedya, a v sozvezdii Shita nablyudaetsya Novaya zvezda (slabee 10m).
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya k koncu nedeli do 38 gradusov, a dolgota dnya na toi zhe shirote - do 13 chasov 10 minut. Vidimyi diametr Solnca za opisyvaemyi period uvelichitsya do 31,77 minut dugi, a dvizhetsya ono po sozvezdiyu L'va. Tekushie dannye o Solnce i vid ego poverhnosti na dannoe vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 6 sentyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Kozeroga, Vodoleya, Ryb, Ovna i Tel'ca, izmenyaya fazu ot 0,95+ do 1,0, a posle polnoluniya do 0,75- i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Kozeroga, ostavayas' v nem do 5 sentyabrya, kogda vstupit v sozvezdie Vodoleya, gde primet fazu polnoluniya 6 sentyabrya. V eto polnolunie proizoidet pokrytie Lunoi planety Neptun pri vidimosti v Yuzhnoi Amerike i Antarktide. Granicu sozvezdiya Ryb pochti polnaya Luna peresechet 7 sentyabrya, a 8 i 10 sentyabrya posetit sozvezdie Kita. Umen'shaya fazu, lunnyi oval 9 sentyabrya vnov' pobyvaet v sozvezdii Ryb, proidya yuzhnee Urana pri faze okolo 0,9- 9 sentyabrya. Zaidya nenadolgo v sozvezdie Ovna v noch' s 10 na 11 sentyabrya, Luna pereidet v sozvezdie Tel'ca pri faze okolo 0,7-. Faza Luny na tekushii moment. Fazy Luny na budushee.

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 4 sentyabrya - v 1728 godu, 5 sentyabrya - v 0248 godu, 6 sentyabrya - v 1755 godu, 7 sentyabrya - v 1858 godu, 8 sentyabrya - v 1885 godu, 9 sentyabrya - v 1904 godu, 10 sentyabrya - v 1923 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 4 sentyabrya (7 zatmenii!), a men'she vsego 5 sentyabrya (1 zatmenie). 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. Kosmicheskie issledovaniya - Novye Gorizonty .
