Na dannoi nedele 4 dekabrya Luna (F= 0,61-) proidet severnee Regula, a Merkurii dostignet maksimal'noi vostochnoi (vechernei) elongacii 21 gradus. V etot zhe den' Luna (F= 0,54-) dostignet apogeya svoei orbity na rasstoyanii 404348 km ot centra Zemli, a 6 dekabrya Neptun proidet stoyanie s perehodom k pryamomu dvizheniyu. 8 dekabrya nastupit maksimum deistviya meteornogo potoka Monocerotidy (ZHR= 2) iz sozvezdiya Edinoroga, a Mars proidet v 4,3 gr. severnee Antaresa. V etot zhe den' Luna (F= 0,20-) okazhetsya v nishodyashem uzle svoei orbity (severnee Spiki), a 9 dekabrya Luna (F= 0,12-) proidet yuzhnee Venery. Krome etogo, na nochnom nebe bliz Vegi nablyudaetsya kometa P/Pons-Brooks (12P), kotoraya uvelichila yarkost' do 9m.

Vidimyi diametr Solnca uvelichivaetsya ot 32,45 do 32,48 minut dugi, a dvizhetsya ono po sozvezdiyu Zmeenosca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 5 dekabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya L'va, Devy i Vesov, izmenyaya fazu ot 0,61- do 0,05- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii L'va. 4 dekabrya lunnyi oval (F= 0,61-) proidet severnee Regula, a 5 dekabrya primet v sozvezdii L'va fazu poslednei chetverti. 6 dekabrya Luna (F= 0,42-) pereidet v sozvezdie Devy. Zdes' 8 dekabrya Luna (F= 0,2-) proidet severnee Spiki, a 9 dekabrya proidet yuzhnee Venery pri faze 0,12-. V etot zhe den' lunnyi serp (F= 0,11-) pereidet v sozvezdie Vesov, a 11 dekabrya pri faze 0,03- dostignet sozvezdiya Skorpiona. Fazy Luny na dannoe vremya i na budushee.
