Astronomicheskaya nedelya s 21 po 27 maya 2018 goda17.05.2018 16:44 | Aleksandr Kozlovskii
Na dannoi nedele proizoidet pokrytie Lunoi (F= 0,44+) zvezdy psi L'va (5,4m) pri vidimosti v Sibiri i na Severe strany. 22 maya Luna sblizitsya Regulom pri faze pervoi chetverti, a 25 maya pri faze 0,86 - so Spikoi. 27 maya yarkii lunnyi disk (F= 0,96+) proidet bliz Yupitera. Krome etogo, nachinaetsya sezon serebristyh oblakov, kotorye poyavlyayutsya na fone vechernih i utrennih sumerek. Vesta dostigla 6 zvezdnoi velichiny i mozhet byt' naidena nevooruzhennym glazom pri blagopriyatnyh usloviyah.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 55 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 55 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shitsya 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 pervoi chetverti 22 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Raka, L'va, Devy i Vesov, izmenyaya fazu ot 0,4+ do 1 i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Raka. 21 maya lunnyi oval pereidet vo vladeniya sozvezdiya L'va pri faze 0,4+ i poidet na sblizhenie s Regulom, severnee kotorogo proidet 22 maya, vstupiv v fazu pervoi chetverti. V sozvezdie Devy yarkii lunnyi oval (F= 0,67+) pereidet 23 maya, gde 26 maya proidet severnee Spiki pri faze 0,87+, nablyudayas' dostatochno nizko nad gorizontom. 27 maya yarkii lunnyi disk (F= 0,93+) pereidet v sozvezdie Vesov, i v etot zhe den' proidet severnee Yupitera pri faze 0,96+. Faza Luny na dannoe vremya i na budushee.

Karty putei komet i asteroidov na mesyac imeyutsya v KN na mai, a na drugie periody - v Astronomicheskom kalendare na 2018 god. Podrobnye svedeniya o kometah nedeli i mesyaca (s kartami i prognozami bleska) privodyatsya na http://aerith.net/comet/weekly/current.html , a rezul'taty nablyudenii na http://195.209.248.207/ .
Sredi asteroidov naibolee yarkimi i udobnymi dlya nablyudenii na dannoi nedele budut: Cerera (8,6m) v sozvezdii L'va i Vesta (5,9m) v sozvezdii Strel'ca. Vestu pri blagopriyatnyh usloviyah mozhno naiti nevooruzhennym glazom.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: SV Andromedy 8,7m - 21 maya, RY Gerkulesa 9,0m - 25 maya, S Sekstanta 9,1m - 27 maya.

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 21 maya ne bylo, 22 maya - v 1724 godu, 23 maya - v 1221 godu, 24 maya - v 1789 godu, 25 maya - v 1770 godu, 26 maya - v 1397 godu, 27 maya - v 1435 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 25 maya (9 zatmenii!), a men'she vsego 21 maya (ne bylo). Your Guide to the 2017 Total Solar Eclipse
