Astronomicheskaya nedelya s 18 po 24 iyunya 2018 goda15.06.2018 8:01 | Aleksandr Kozlovskii
Na dannoi nedele Luna (F= 0,25+) proidet severnee Regula (18 iyunya), a 19 iyunya Neptun dostignet stoyaniya s perehodom k popyatnomu dvizheniyu. V etot zhe den' Vesta proidet protivostoyanie s Solncem, a dolgoperiodicheskaya peremennaya zvezda T Cefeya dostignet maksimuma bleska (5m). 20 iyunya Venera proidet cherez zvezdnoe skoplenie Yasli (M44), a na sleduyushii den' nastupit letnee solncestoyanie. V konce nedeli Luna (F= 0,83+) proidet severnee Yupitera. Krome etogo, prodolzhaetsya sezon serebristyh oblakov, kotorye poyavlyayutsya na fone vechernih i utrennih sumerek. Vesta imeet blesk yarche 6 zvezdnoi velichiny i mozhet byt' naidena nevooruzhennym glazom pri blagopriyatnyh usloviyah.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy imeet znachenie 57 gradusov, a dolgota dnya na toi zhe shirote - 17 chasov 30 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shitsya do 31,47 minut dugi, a dvizhetsya ono po sozvezdiyu Tel'ca, 21 iyunya perehodya v sozvezdie Bliznecov. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 20 iyunya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya L'va, Devy i Vesov, izmenyaya fazu ot 0,20+ do 0,90+ i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii L'va bliz Regula, severnee kotorogo proidet 18 iyunya. V sozvezdie Devy lunnyi pochti poludisk (F= 0,45+) pereidet okolo grinvichskoi polunochi 20 iyunya, gde v etot zhe den' primet fazu pervoi chetverti. 22 iyunya lunnyi oval pri faze blizkoi k 0,7+ proidet severnee Spiki, nablyudayas' dostatochno nizko nad gorizontom. 23 iyunya yarkii lunnyi oval (F= 0,78+) pereidet v sozvezdie Vesov, i v etot zhe den' proidet severnee Yupitera pri faze 0,83+. Faza Luny na dannoe vremya i na budushee.

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 18 iyunya - v 1471 godu, 19 iyunya - v 1936 godu, 20 iyunya - v 1974 godu, 21 iyunya - v 2001 godu, 22 iyunya - v 1229 godu, 23 iyunya - v 0168 godu, 24 iyunya - v 1797 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 21 iyunya (7 zatmenii!), a men'she vsego 23 iyunya (2 zatmenIYa). Your Guide to the 2017 Total Solar Eclipse
