3.12.2021 6:16 | Aleksandr Kozlovskii
Na dannoi nedele 6 dekabrya Luna (F= 0,05+) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora, a 7 dekabrya pri faze 0,11+ budet nahodit'sya yuzhnee Venery. 8 dekabrya nastupit maksimum deistviya meteornogo potoka Monocerotidy (ZHR= 2) iz sozvezdiya Edinoroga, a Luna (F= 0,2+) proidet yuzhnee Saturna. 9 dekabrya Luna (F= 0,31+) budet nablyudat'sya yuzhnee Yupitera, a 11 dekabrya pri faze pervoi chetverti proidet yuzhnee Neptuna. V etot zhe den' asteroid Nysa (44) vstupit v protivostoyanie s Solncem, a 12 dekabrya dolgoperiodicheskaya peremennaya zvezda R Malogo Psa dostignet maksimuma bleska (6,5m). Krome etogo, kometa Leonard (C/2021 A1) pri bleske okolo 6m imeet dvoinuyu (utrennyuyu i vechernyuyu)vidimost'.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 11 gradusov, a dolgota dnya na toi zhe shirote - do 7 chasov 05 minut. Vidimyi diametr Solnca uvelichivaetsya do 32,48 minut dugi, a dvizhetsya ono po sozvezdiyu Zmeenosca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 11 dekabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Strel'ca, Kozeroga, Vodoleya i Ryb, izmenyaya fazu ot 0,01+ do 0,7+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Strel'ca. 7 dekabrya Luna (F= 0,11+) sblizitsya s Veneroi, a zatem pri faze 0,14+ pereidet v sozvezdie Kozeroga. Zdes' Luna (F= 0,2+) proidet yuzhnee Saturna 8 dekabrya, a na sleduyushii den' pri faze 0,31+ - yuzhnee Yupitera, perehodya zatem v sozvezdie Vodoleya. 11 dekabrya Luna v etom sozvezdii primet fazu pervoi chetverti, nahodyas' yuzhnee Neptuna, v etot zhe den' vstupiv sozvezdie Ryb pri faze 0,56+. 12 dekabrya Luna (F= 0,63+) dostignet sozvezdiya Kita. Fazy Luny na dannoe vremya i na budushee.
Iz planet Solnechnoi sistemy: Merkurii ne viden, a Veneru mozhno naiti na vechernem nebe. Mars nablyudaetsya na fone utrennei zari, a Yupiter i Saturn vidny vecherom i noch'yu. Uran i Neptun mozhno nablyudat' v binokl' v nochnoe vremya. Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v pechatnoi versii v AK_2021 na http://www.astronet.ru/db/msg/1704127. Efemeridy Solnca, Luny i planet na kazhdyi den' - http://astropixels.com/.
Iz komet (naibolee dostupnyh dlya lyubitelei astronomii) hvostataya strannica P/Churyumov-Gerasimenko (67P) s bleskom okolo 10m peremeshaetsya po sozvezdiyu Raka, a kometa Leonard (C/2021 A1) dvizhetsya po sozvezdiyam Volopasa, Zmei, Gerkulesa i Zmeenosca pri bleske okolo 6m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na dekabr', a na drugie periody - v Astronomicheskom kalendare na 2021 god. Podrobnye svedeniya o kometah nedeli i mesyaca (s kartami i prognozami bleska) privodyatsya na http://aerith.net/comet/weekly/current.html , a rezul'taty nablyudenii - na http://195.209.248.207/ .
Sredi asteroidov naibolee yarkoi na dannoi nedele budet Cerera (7,2m) v sozvezdii Tel'ca (bliz Giad i Pleyad).
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: R Mikroskopa 8,8m - 11 dekabrya i R Malogo Psa 7,5m - 12 dekabrya.
