Astronomicheskaya nedelya s 10 po 16 maya 2021 goda7.05.2021 7:01 | Aleksandr Kozlovskii
Na dannoi nedele 10 maya Luna (F= 0,01-) proidet yuzhnee Urana, a 11 maya Luna (F= 0,0) okazhetsya v apogee svoei orbity na rasstoyanii 406510 km ot centra Zemli. 12 maya Luna (F= 0,01+) budet nahodit'sya bliz Pleyad i Venery (pokrytie, vidimoe v akvatorii Tihogo okeana), a 13 maya pri faze 0,02+ proidet severnee Al'debarana okolo voshodyashego uzla svoei orbity i bliz Merkuriya. 14 maya proizoidet pokrytie Lunoi (F= 0,07+) zvezdy 121 Tel'ca (5,4m) pri vidimosti v Sibiri, a 15 maya Luna (F= 0,14+) proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora. 16 maya dolgoperiodicheskaya peremennaya zvezda R Zmei dostignet maksimuma bleska (5m), a Luna (F= 0,17+) proidet severnee Marsa. 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 uvelichivaetsya do 53 gradusov, a dolgota dnya na toi zhe shirote vozrastaet do 16 chasov 25 minut. Vidimyi diametr Solnca umen'shaetsya do 31,64 minut dugi, a dvizhetsya ono po sozvezdiyu Ovna, 14 maya perehodya v sozvezdie Tel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 11 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Ryb, Ovna, Tel'ca i Bliznecov, izmenyaya fazu ot 0,03- do 0,2+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Ryb. 10 maya lunnyi serp (F= 0,03-) posetit sozvezdie Kita, kotoroe pokinet v etot zhe den' pri faze 0,01-, pereidya v sozvezdie Ovna i nahodyas' bliz Urana. V etom sozvezdii Luna 11 maya primet fazu novoluniya, pereidya na vechernee nebo, i vstupiv v sozvezdie Tel'ca. Zdes' 12 maya rastushii serp (F= 0,01+) budet nablyudat'sya bliz rasseyannogo zvezdnogo skopleniya Pleyady i Venery. 13 maya Luna sblizitsya s Giadami, a zatem s Merkuriem, uvelichiv fazu do 0,03+. 15 maya molodoi mesyac dostignet sozvezdiya Bliznecov pri faze 0,1+ i probudet zdes' do 17 maya. 16 maya Luna proidet severnee Marsa pri faze 0,17+, a pokinet sozvezdie Bliznecov uzhe pri faze 0,26+. Fazy Luny na dannoe vremya i na budushee.
Iz planet Solnechnoi sistemy: Merkurii, Veneru i Mars mozhno nablyudat' po vecheram, a Yupiter i Saturn imeyut nochnuyu i utrennyuyu vidimost'.

Sredi asteroidov naibolee yarkoi na dannoi nedele budet Vesta (7,1m) v sozvezdii L'va.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: X Andromedy 9,0m - 10 maya, S Bol'shoi Medvedicy 8,0m - 12 maya, ST Andromedy 9,0m - 14 maya, R Zmei 6,3m - 16 maya.
