Astronomicheskaya nedelya s 7 po 13 iyunya 2021 goda4.06.2021 7:01 | Aleksandr Kozlovskii
Na dannoi nedele 7 iyunya lunnyi serp (F= 0,09-) proidet yuzhnee Urana, a 8 iyunya Luna (F= 0,05-) okazhetsya v apogee svoei orbity na rasstoyanii 406223 km ot centra Zemli, proidya v etot den' pri faze 0,02- yuzhnee Pleyad. 9 iyunya Luna (F= 0,01-) dostignet voshodyashego uzla svoei orbity, proidya severnee Al'debarana. 10 iyunya nastupit novolunie i proizoidet kol'ceobraznoe solnechnoe zatmenie (vidimoe v Rossii). V etot zhe den' Luna (F= 0,0) proidet bliz Merkuriya, kotoryi 11 iyunya dostignet nizhnego soedineniya s Solncem. 12 iyunya molodaya Luna (F= 0,03+) proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora, a dolgoperiodicheskaya peremennaya zvezda U Oriona dostignet maksimuma bleska (6m). V etot zhe den' Luna (F= 0,03+) proidet bliz Venery, a takzhe proizoidet pokrytie Lunoi (F= 0,03+) zvezdy epsilon Bliznecov (3,0m) pri vidimosti v Sibiri i na Dal'nem Vostoke. 13 iyunya Luna (F= 0,11+) proidet severnee Marsa. 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 vozrastaet do 17 chasov 30 minut. Vidimyi diametr Solnca umen'shaetsya do 31,49 minut dugi, a dvizhetsya ono po sozvezdiyu Tel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 10 iyunya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Ovna, Tel'ca, Bliznecov i Raka, izmenyaya fazu ot 0,1- do 0,1+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii (do 12 iyunya, a zatem - umen'shaya). Nachalo nedeli nochnoe svetilo provedet v sozvezdii Ovna. 7 iyunya Luna pri faze 0,09- proidet yuzhnee Urana i ustremitsya k sozvezdiyu Tel'ca, v kotoroe voidet uzhe 8 iyunya pri faze 0,05-. V etot den' tayushii lunnyi serp (F= 0,02-) budet nablyudat'sya bliz rasseyannogo zvezdnogo skopleniya Pleyady, a 9 iyunya Luna sblizitsya s Giadami. 10 iyunya nastupit novolunie i proizoidet kol'ceobraznoe solnechnoe zatmenie s maksimal'noi fazoi 0,944 (vidimost' na Dal'nem Vostoke). Chastnye fazy etogo zatmeniya mozhno budet nablyudat' pochti na vsei territorii Rossii i SNG. 11 iyunya molodoi mesyac dostignet sozvezdiya Bliznecov pri faze 0,01+ i probudet zdes' do 13 iyunya, 12 iyunya proidya severnee Venery pri faze 0,03+. 13 iyunya molodoi mesyac peresechet granicu sozvezdiya Raka, gde proidet severnee Marsa pri faze 0,11+. 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.

Sredi asteroidov naibolee yarkoi na dannoi nedele budet Vesta (7,5m) v sozvezdii L'va.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: RY Gerkulesa 8,9m - 9 iyunya, V Kozeroga 8,7m - 9 iyunya, U Oriona 6,8m - 12 iyunya, W Pegasa 8,6m - 12 iyunya.
