Astronomicheskaya nedelya so 2 po 8 dekabrya 2019 goda Astronomicheskaya nedelya so 2 po 8 dekabrya 2019 goda
29.11.2019 6:10 | Aleksandr Kozlovskii

Na dannoi nedele 2 dekabrya asteroid Kloto (97) vstupit v protivostoyanie s Solncem, a 3 dekabrya proizoidet pokrytie etim asteroidom na 13 sekund zvezdy HIP21894 (6,9m) iz sozvezdiya Eridana pri vidimosti v Zabaikal'e, Habarovskom krae i na Kamchatke. 4 dekabrya Luna (F= 0,53+) proidet bliz Neptuna, a 5 dekabrya Luna (F= 0,58+) dostignet apogeya svoei orbity na rasstoyanii 404445 km ot centra Zemli i proizoidet pokrytie Lunoi (F= 0,63+) zvezd 30 Ryb (4,4m) i 33 Ryb (4,6m) pri vidimosti na Evropeiskoi chasti Rossii i v Sibiri. 7 dekabrya dolgoperiodicheskaya peremennaya zvezda R L'va dostignet maksimuma bleska (5m), a 8 dekabrya meteornyi potok Monocerotidy (ZHR= 2) iz sozvezdiya Edinoroga dostignet maksimuma deistviya. V etot zhe den' Luna (F= 0,87+) proidet bliz Urana.

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 12 gradusov, a dolgota dnya na toi zhe shirote - do 7 chasov 10 minut. Vidimyi diametr Solnca uvelichivaetsya do 32,47 minut dugi, a dvizhetsya ono po sozvezdiyu Zmeenosca. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 4 dekabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Kozeroga, Vodoleya i Ryb, izmenyaya fazu ot 0,3+ do 0,9+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Kozeroga. Zdes' nochnoe svetilo probudet do polunochi 3 dekabrya, a zatem pri faze 0,38+ pereidet v sozvezdie Vodoleya. Zdes' 4 dekabrya Luna primet fazu pervoi chetverti, a zatem (F= 0,53+) proidet yuzhnee Neptuna. V sozvezdii Vodoleya 5 dekabrya lunnyi oval pri faze 0,58+ dostignet apogeya svoei orbity na rasstoyanii 404445 km ot centra Zemli, pereidya v etot zhe den' v sozvezdie Ryb pri faze 0,62+. 5 dekabrya proizoidet pokrytie Lunoi (F= 0,63+) zvezd 30 Ryb (4,4m) i 33 Ryb (4,6m) pri vidimosti na Evropeiskoi chasti Rossii i v Sibiri. 6 dekabrya yarkaya Luna pereidet v sozvezdie Kita pri faze 0,68+, a 7 dekabrya (F= 0,78+) snova posetit sozvezdie Ryb. 8 dekabrya nochnoe svetilo (F= 0,86+) proidet yuzhnee Urana, a zatem eshe raz posetit sozvezdie Kita. Fazy Luny na dannoe vremya i na budushee.

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 2 dekabrya - v 1518 godu, 3 dekabrya - 0978 godu, 4 dekabrya - v 2002 godu, 5 dekabrya - v 1676 godu, 6 dekabrya - v 1695 godu, 7 dekabrya - v 0633 godu, 8 dekabrya - v 0215 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 5 dekabrya (8 zatmenii), a men'she vsego 7 i 8 dekabrya (po 1 zatmeniyu). Your Guide to the 2017 Total Solar Eclipse
