Astronomicheskaya nedelya s 30 dekabrya 2019 goda po 5 yanvarya 2020 goda27.11.2019 6:40 | Aleksandr Kozlovskii
Na dannoi nedele 31 dekabrya Luna (F= 0,3+) proidet bliz Neptuna, a 2 yanvarya nochnoe svetilo okazhetsya (F= 0,4+) v apogee svoei orbity na rasstoyanii 404576 km ot centra Zemli. V etot zhe den' Merkurii proidet v polutora gradusah yuzhnee Yupitera, a 3 yanvarya nastupit maksimum deistviya meteornogo potoka Kvadrantidy (ZHR= 120) iz sozvezdiya Volopasa. 4 yanvarya Luna (F= 0,66+) proidet bliz Urana, a 5 yanvarya Zemlya dostignet perigeliya svoei orbity na rasstoyanii 0,9832436 a.e. ot Solnca.

Vidimyi diametr Solnca uvelichivaetsya do 32,54 minut dugi, a dvizhetsya ono po sozvezdiyu Strel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 3 yanvarya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Kozeroga, Vodoleya i Ovna, izmenyaya fazu ot 0,15+ do 0,75+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Kozeroga. 30 dekabrya pri faze 0,17+ rastushii serp dostignet sozvezdiya Vodoleya, nablyudayas' na fone vechernei zari. Zdes' 31 dekabrya Luna pri faze 0,3+ proidet yuzhnee Neptuna i zakonchit svoi put' po nebu 2019 goda.
