• >> Astronomicheskaya nedelya s 21 po 27 iyunya 2021 goda   (Aleksandr Kozlovskii, 18.06.2021 6:01, 20.8 KBait, otvetov: 3)

  Na dannoi nedele 21 iyunya nastupit letnee solncestoyanie. Solnce v etot den' (podnimayas' k severu ot nebesnogo ekvatora) kak by zamiraet v verhnei tochke maksimal'nogo skloneniya (+23,5 gradusa), a zatem nachinaet opuskat'sya k yugu (postepenno sblizhayas' s nebesnym ekvatorom, peresechenie kotorogo proizoidet 22 sentyabrya). Privedennye dannye po prodolzhitel'nosti dnya spravedlivy dlya shiroty Moskvy, gde poludennaya vysota Solnca v techenie mesyaca imeet znachenie okolo 57 gradusov. Na shirote S._Peterburga nastupayut belye nochi, a severnee 66 shiroty idet polyarnyi den'. Dostatochno blagopriyatnye usloviya dlya nablyudeniya zvezdnogo neba ostayutsya lish' v yuzhnyh shirotah strany. Dlya srednih shirot glubokoe zvezdnoe nebo otkroetsya lish' k koncu iyulya. 21 iyunya Yupiter dostignet stoyaniya s perehodom k popyatnomu dvizheniyu, a Venera proidet v 5,2 gr. yuzhnee Polluksa. V etot zhe den' proizoidet pokrytie Lunoi (F= 0,87+) zvezdy nyu Vesov (5,2m) pri vidimosti na Evropeiskoi chasti Rossii, a 22 iyunya Merkurii dostignet stoyaniya s perehodom k pryamomu dvizheniyu. 23 iyunya Luna (F= 0,96+) proidet severnee Antaresa okolo nishodyashego uzla svoei orbity i perigeya na rasstoyanii 359953 km ot centra Zemli. 25 iyunya Luna (F= 1,0) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora, a 26 iyunya Neptun dostignet stoyaniya s perehodom k popyatnomu dvizheniyu. 27 iyunya meteornyi potok Iyun'skie Bootidy dostignet maksimuma deistviya (potok peremennyi, ZHR= 0 - 100), a Luna (F= 0,90-) proidet yuzhnee Saturna. Vsyu nedelyu vozmozhno poyavlenie serebristyh oblakov na fone sumerechnogo segmenta. Krome etogo, idet period, kogda yarkie sputniki Yupitera tesno sblizhayutsya i pokryvayutsya drug drugom.

  Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy priderzhivaetsya znacheniya 57 gradusov, a dolgota dnya na toi zhe shirote sostavlyaet okolo 17 chasov 30 minut. Vidimyi diametr Solnca umen'shaetsya do 31,47 minut dugi, a dvizhetsya ono po sozvezdiyu Bliznecov. Dannye o Solnce na tekushee vremya.

  Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 24 iyunya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Devy, Vesov, Skorpiona, Zmeenosca, Strel'ca i Kozeroga, izmenyaya fazu ot 0,8+ do 1, a zatem do 0,85-, i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii (s 25 iyunya - uvelichivaya). Nachalo nedeli nochnoe svetilo provedet v sozvezdii Devy. V sozvezdie Vesov lunnyi oval voidet 21 iyunya pri faze 0,8+. 22 iyunya pochti polnaya Luna pereidet v sozvezdie Skorpiona pri faze 0,94+, a 23 iyunya pri faze 0,96+ vstupit v sozvezdie Zmeenosca. 24 iyunya yarkii lunnyi disk pereidet v sozvezdie Strel'ca i primet zdes' fazu polnoluniya. V etom sozvezdii Luna probudet do 26 iyunya, kogda pereidet v sozvezdie Kozeroga pri faze 0,96-. Zdes' nochnoe svetilo (F= 0,9-) 27 iyunya proidet yuzhnee Saturna. Fazy Luny na dannoe vremya i na budushee.

  Iz planet Solnechnoi sistemy: Merkurii ne viden, a Veneru i Mars mozhno nablyudat' na fone vechernei zari. Yupiter i Saturn vidny bol'shuyu chast' nochi. Uran i Neptun nahodyatsya na utrennem sumerechnom nebe. Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v pechatnoi versii v AK_2021 na http://www.astronet.ru/db/msg/1704127.

  Iz komet hvostataya strannica Palomar (C/2020 T2) s bleskom okolo 11m peremeshaetsya po sozvezdiyu Volopasa. Karty putei komet i asteroidov na mesyac imeyutsya v KN na iyun', a na drugie periody - v Astronomicheskom kalendare na 2021 god.

  Sredi asteroidov naibolee yarkoi na dannoi nedele budet Vesta (7,6m) v sozvezdii L'va.

  Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: T Strel'ca 8,5m - 23 iyunya i U Kormy 8,5m - 26 iyunya.
