- Astronomicheskaya nedelya s 12 po 18 aprelya 2021 goda
(Aleksandr Kozlovskii,
9.04.2021 9:40, 20.0 KBait, otvetov: 5)
Na dannoi nedele 12 aprelya (60 let pervomu poletu cheloveka v kosmos) Luna (F= 0,01+) proidet yuzhnee Venery, a 13 aprelya pri faze 0,02+ - yuzhnee Urana. 14 aprelya Luna (F= 0,06+) dostignet apogeya svoei orbity na rasstoyanii 406120 km ot centra Zemli, a 15 aprelya Luna (F= 0,1+) proidet yuzhnee rasseyannogo zvezdnogo skopleniya Pleyady. 16 aprelya Luna (F= 0,15+) proidet severnee Al'debarana bliz voshodyashego uzla svoei orbity, a Yupiter sblizitsya so zvezdoi myu Kozeroga do poloviny uglovoi minuty. 17 aprelya dolgoperiodicheskaya peremennaya zvezda R Treugol'nika dostignet maksimuma bleska (5m), a Luna (F= 0,24+) proidet yuzhnee Marsa (pokrytie, vidimoe v Indii i stranah Yugo-Vostochnoi Azii). 18 aprelya lunnyi serp (F= 0,34+) proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora, pokryv pri etom zvezdu epsilon Bliznecov (3,1m) pri vidimosti v zapadnoi polovine strany. Krome etogo, idet period, kogda yarkie sputniki Yupitera pokryvayutsya drug drugom. Tak 12 aprelya Io budet nahodit'sya v 4 uglovyh sekundah ot Ganimeda i ot Kallisto. 15 aprelya Io pochti kosnetsya Ganimeda, a 17 aprelya Evropa i Io sol'yutsya v odno celoe pri malyh uvelicheniyah.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 45 gradusov, a dolgota dnya na toi zhe shirote vozrastaet do 14 chasov 25 minut. Vidimyi diametr Solnca umen'shaetsya do 31,85 minut dugi, a dvizhetsya ono po sozvezdiyu Ryb (do 18 aprelya, perehodya zatem v sozvezdie Ovna). Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 12 aprelya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Ryb, Ovna, Tel'ca i Bliznecov, izmenyaya fazu ot 0 do 0,4+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Ryb, nahodyas' ryadom s Veneroi. 13 aprelya lunnyi serp (F= 0,01+) eshe raz posetit sozvezdie Kita, kotoroe pokinet v etot zhe den' pri faze 0,02+, pereidya v sozvezdie Ovna i nahodyas' bliz Urana. 14 aprelya Luna pereidet v sozvezdie Tel'ca pri faze 0,05+, proidya na sleduyushii den' yuzhnee Pleyad pri faze 0,08+. 15 aprelya lunnyi serp (F= 0,15+) budet nahodit'sya severnee Al'debarana i rasseyannogo zvezdnogo skopleniya Giady. Prodolzhiv put' po sozvezdiyu Tel'ca, Luna (F= 0,24+) 17 aprelya proidet yuzhnee Marsa, vstupiv v etot zhe den' v sozvezdie Bliznecov. Fazy Luny na dannoe vremya i na budushee.

Sredi asteroidov naibolee yarkoi na dannoi nedele budet Vesta (6,6m) v sozvezdii L'va.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: R Vorona 8,6m - 12 aprelya, R Treugol'nika 6,1m - 17 aprelya, T Vodoleya 8,2m - 17 aprelya, R Zhirafa 9,0m -18 aprelya.
