Astronomicheskaya nedelya s 14 po 20 iyunya 2021 goda11.06.2021 6:10 | Aleksandr Kozlovskii
Na dannoi nedele 14 iyunya Luna (F= 0,14+) proidet severnee zvezdnogo skopleniya Yasli (M44), a 16 iyunya pri faze 0,29+ - severnee Regula. 19 iyunya dolgoperiodicheskaya peremennaya zvezda T Centavra dostignet maksimuma bleska (5m), a 20 iyunya Luna (F= 0,70+) proidet severnee Spiki. V etot zhe den' dolgoperiodicheskaya peremennaya zvezda RS Vesov dostignet maksimuma bleska (7m). 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 31,48 minut dugi, a dvizhetsya ono po sozvezdiyu Tel'ca do 20 iyunya, a zatem perehodit v sozvezdie Bliznecov. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 18 iyunya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Raka, L'va i Devy, izmenyaya fazu ot 0,1+ do 0,8+ i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Raka. 14 iyunya Luna (F= 0,14+) proidet severnee rasseyannogo zvezdnogo skopleniya Yasli (M44), a na sleduyushii den' pereidet v sozvezdie L'va, uvelichiv fazu do F= 0,2+. 16 iyunya Luna (F= 0,29+) proidet severnee Regula, a zatem ustremitsya k sozvezdiyu Devy, v kotoroe voidet 17 iyunya pri faze 0,46+. Zdes' 18 iyunya Luna primet fazu pervoi chetverti, a 20 iyunya (F= 0,7+) proidet severnee Spiki, ustremivshis' k sozvezdiyu Vesov, v kotoroe voidet 21 iyunya pri faze 0,8+. 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 (7,6m) v sozvezdii L'va.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: S Bliznecov 8,7m - 17 iyunya, Z Lebedya 8,2m - 19 iyunya, T Centavra 6,5m - 19 iyunya, RS Vesov 7,9m - 20 iyunya.
