Astronomicheskaya nedelya s 20 po 26 maya 2024 goda15.05.2024 13:01 | Aleksandr Kozlovskii
Vopros nedeli. Byl li Sirius kogda-nibud' krasnym?
Otvety mozhno davat' v kommentariyah k dannoi stranichke.
Na dannoi nedele 20 maya Luna (F= 0,9+) proidet severnee Spiki, a 23 maya Venera proidet v 0,2 gr. severnee Yupitera. 24 maya Luna (F= 0,99-) proidet bliz Antaresa (pokrytie pri vidimosti v Amerike i Afrike). 25 maya budet imet' mesto maksimal'naya zapadnaya libraciya Luny po dolgote 5,3 gr., a pri faze 0,94- nochnoe svetilo proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora. 26 maya budet imet' mesto maksimal'naya severnaya libraciya Luny po shirote 6,7 gr. Krome etogo, imeetsya vozmozhnost' poyavleniya serebristyh oblakov na fone utrennih i vechernih sumerek.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya ot 54 do 55 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 55 minut. Vidimyi diametr Solnca umen'shaetsya ot 31,61 do 31,57 minut dugi, a dvizhetsya ono po sozvezdiyu Tel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 23 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Devy, Vesov, Skorpiona, Zmeenosca i Strel'ca, izmenyaya fazu ot 0,88+ do 0,87- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Devy. 20 maya nochnoe svetilo (F= 0,9+) proidet severnee Spiki, a 21 maya pri faze 0,96+ vstupit v sozvezdie Vesov, gde probudet do 23 maya. V etot den' nochnoe svetilo vstupit v sozvezdie Skorpiona, gde primet fazu polnoluniya (nablyudayas' vsyu noch'). 24 maya Luna (F= 0,99-) pokroet Antares pri vidimosti v Amerike i Afrike, a zatem pereidet v sozvezdie Zmeenosca. 25 maya Luna (F= 0,96-) vstupit v sozvezdie Strel'ca, gde probudet do 27 maya, kogda pereidet v sozvezdie Kozeroga pri faze 0,81-. Fazy Luny na dannoe vremya i na budushee.
Iz planet Solnechnoi sistemy: Merkurii, Venera, Mars, Saturn i Neptun nahodyatsya na utrennem nebe (luchshaya vidimost' v yuzhnyh shirotah), a Yupiter i Uran ne vidny. Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v Astronomicheskih kalendaryah na blizhaishie gody. Efemeridy Solnca, Luny i planet na kazhdyi den' - http://astropixels.com/.
