Astronomicheskaya nedelya s 23 po 29 iyulya 2018 goda20.07.2018 5:32 | Aleksandr Kozlovskii
Na dannoi nedele (nasyshennoi astronomicheskimi yavleniyami) dolgoperiodicheskaya peremennaya zvezda R Orla dostignet maksimuma bleska (5m), a 25 iyulya Luna (F= 0,93+) proidet severnee Saturna. 25 iyulya Merkurii okazhetsya v stoyanii s perehodom ot pryamogo dvizheniya k popyatnomu, a Luna (F= 0,95+) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora. 27 iyulya nastupit velikoe protivostoyanie Marsa pri polnom lunnom zatmenii (samoe prodolzhitel'noe lunnoe zatmenie v tekushem stoletii - 103 minuty) pri vidimosti v Rossii (!!). V etot zhe den' Luna (F= 1,0) proidet apogei svoei orbity na rasstoyanii 406220 km ot centra Zemli bliz nishodyashego uzla svoei orbity. 27 iyulya dolgoperiodicheskaya peremennaya zvezda R Andromedy dostignet maksimuma bleska (6m). Krome etogo, prodolzhaetsya sezon serebristyh oblakov, kotorye poyavlyayutsya na fone vechernih i utrennih sumerek. Vesta imeet blesk okolo 6 zvezdnoi velichiny i mozhet byt' naidena nevooruzhennym glazom pri blagopriyatnyh usloviyah.
Stat'i o lunnyh zatmeniyah na Astronet: http://www.astronet.ru/db/msg/1208455 i http://www.astronet.ru/db/msg/1341897
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 53 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 10 minut. Vidimyi diametr Solnca za opisyvaemyi period uvelichivaetsya do 31,50 minut dugi, a dvizhetsya ono po sozvezdiyu Raka. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 27 iyulya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Skorpiona, Zmeenosca, Strel'ca, Kozeroga i Vodoleya, izmenyaya fazu ot 0,8+ do 1,0 i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii (do serediny nedeli, a zatem uvelichivaya). Nachalo nedeli nochnoe svetilo provedet v sozvezdii Skorpiona. 23 iyulya Luna pri faze 0,8+ peresechet granicu s sozvezdiem Zmeenosca, i budet nablyudat'sya nizko nad gorizontom pochti vsyu noch'. 24 iyulya pochti yarkaya Luna (F= 0,9+) pereidet v sozvezdie Strel'ca i sovershit pochti trehdnevnoe puteshestvie po etomu sozvezdiyu, proidya v nachale etogo puti severnee Saturna (bliz maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora), a v konce opisyvaemogo perioda prakticheski dostignuv polnoluniya. No etu fazu nochnoe svetilo primet uzhe v sozvezdii Kozeroga, v kotoroe pereidet 27 iyulya. V eto polnolunie proizoidet polnoe lunnoe zatmenie (samoe prodolzhitel'noe v 21 veke - 103 minuty!!). Krome etogo, etot den' Mars dostignet velikogo protivostoyaniya s Solncem. Zatmivshayasya Luna i Mars v velikom protivostoyanii - ves'ma interesnaya v astronomicheskom i zrelishnom otnoshenii konfiguraciya svetil! Lunnyi disk v eto vremya budet nahodit'sya bliz apogeya svoei orbity. Zakonchiv eto nebesnoe shou, yarkaya Luna ustremitsya k sozvezdiyu Vodoleya, granicu kotorogo peresechet 29 iyulya pri faze 0,97-. Fazy Luny na dannoe vremya i na budushee.
Iz planet Solnechnoi sistemy: Merkurii eshe viden v luchah zahodyashego Solnca v yuzhnyh shirotah. Venera yarko siyaet na fone vechernei zari. Mars, Saturn i Yupiter nablyudayutsya vecherom i noch'yu, a Uran i Neptun mozhno naiti na utrennem nebe. Podrobnye efemeridy i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii AK_2018 na http://www.astronet.ru/db/msg/1364103 . Efemeridy planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ephemeris/ephemeris.html .
Iz komet hvostataya strannica P/Giacobini-Zinner (21P) dvizhetsya po sozvezdiyu Cefeya, imeya blesk okolo 9m. Kometa PANSTARRS (C/2017 S3) dvizhetsya po sozvezdiyu Voznichego pri bleske okolo 9m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na iyul', 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 (8,8m) v sozvezdii L'va i Vesta (6,1m) v sozvezdii Zmeenosca. 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: R Orla 6,1m - 23 iyulya, RV Orla 9,0m - 25 iyulya, R Andromedy 6,9m - 27 iyulya, T Centavra 5,5m - 27 iyulya, S Cefeya 8,3m - 27 iyulya, S Pegasa 8,0m - 27 iyulya.
Nekotorye blizkie pary svetil: Luna - Yupiter, Luna - Antares, Luna - Saturn, Luna - Mars, Venera - Regul, Merkurii - Regul, Saturn - M22, Vesta - teta Zmeenosca, Yupiter - al'fa Vesov, Uran - omikron Ryb, Neptun - lyambda Vodoleya.

Nedel'nyi obzor ot zhurnala "Skai end Teleskop", no nuzhno uchityvat', chto kartinki dayutsya dlya 40 severnoi shiroty, a polozhenie Luny i planet na 7 chasov pozdnee otnositel'no moskovskogo vremeni!
Yasnogo neba i uspeshnyh nablyudenii!
Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 23 iyulya - v 1153 godu, 24 iyulya - v 1702 godu, 25 iyulya - v 1786 godu, 26 iyulya - v 1348 godu, 27 iyulya - v 1832 godu, 28 iyulya - v 1851 godu, 29 iyulya - v 1878 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 23, 27 i 29 iyulya (po 7 zatmenii !), a men'she vsego 28 iyulya (3 zatmeniya).
