Astronomicheskaya nedelya s 15 po 21 marta 2021 goda12.03.2021 6:01 | Aleksandr Kozlovskii
Na dannoi nedele 17 marta Luna (F= 0,12+) proidet yuzhnee Urana, a 18 marta Luna (F= 0,29+) okazhetsya v apogee svoei orbity na rasstoyanii 405254 km ot centra Zemli. 19 marta dolgoperiodicheskaya peremennaya zvezda S Cefeya dostignet maksimuma bleska (6m), a Luna (F= 0,32+) proidet yuzhnee Marsa i severnee Giad (bliz Al'debarana). V etot zhe den' proizoidet pokrytie na 7 sekund zvezdy HIP61099 (7,7m) iz sozvezdiya Volos Veroniki asteroidom (1048) Feodosia pri vidimosti na yuge Evropeiskoi chasti Rossii, a 20 marta Luna (F= 0,36+) dostignet voshodyashego uzla svoei orbity. Vesennee ravnodenstvie v etom godu nastupit 20 marta, i den' stanet ravnym nochi. Solnce v etot den' budet vidno odnovremenno i na yuzhnom i severnom polyusah Zemli. Posle dnya vesennego ravnodenstviya na severnom polyuse Solnce budet nahodit'sya polgoda nad gorizontom, a na yuzhnom - polgoda pod gorizontom.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 34 gradusov, a dolgota dnya na toi zhe shirote vozrastaet do 12 chasov 15 minut. Vidimyi diametr Solnca umen'shaetsya do 32,11 minut dugi, a dvizhetsya ono po sozvezdiyu Ryb. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 21 marta. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Ryb, Ovna, Tel'ca i Bliznecov, izmenyaya fazu ot 0,02+ do 0,55+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Ryb. 16 marta lunnyi serp (F= 0,1+) posetit sozvezdie Kita, kotoroe pokinet 17 marta pri faze 0,12+, pereidya v sozvezdie Ovna i nahodyas' bliz Urana. 18 marta Luna pereidet v sozvezdie Tel'ca pri faze 0,22+, proidya v etot zhe den' yuzhnee Pleyad pri faze 0,25+. 19 marta lunnyi poludisk budet nahodit'sya severnee Giad i Al'debarana, no yuzhnee Marsa pri faze okolo 0,33+. 21 marta nochnoe svetilo pereidet v sozvezdie Bliznecov, prinyav zdes' fazu pervoi chetverti. Fazy Luny na dannoe vremya i na budushee.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: R Bliznecov 7,4m - 15 marta, T Centavra 6,5m - 15 marta, TY Strel'ca 9,1m - 19 marta, S Cefeya 7,1m - 19 marta, W Voznichego 8,6m - 20 marta.
