Na dannoi nedele 20 iyulya Saturn dostignet protivostoyaniya s Solncem, a 21 iyulya Luna (F= 0,01+) proidet severnee zvezdnogo skopleniya Yasli (M44). 22 iyulya dolgoperiodicheskie peremennye zvezdy R Treugol'nika, R Vodoleya i T Cefeya dostignut maksimuma bleska (5m), a Merkurii - maksimal'noi zapadnoi (utrennei) elongacii 20 gradusov. V etot a 23 iyulya dolgoperiodicheskaya peremennaya zvezda W Liry dostignet maksimuma bleska (7m). 24 iyulya dolgoperiodicheskaya peremennaya zvezda V Zmeenosca dostignet maksimuma bleska (6,5m), a 25 iyulya Luna (F= 0,25+) okazhetsya v perigee svoei orbity na rasstoyanii 368359 km ot centra Zemli. V etot zhe den' dolgoperiodicheskaya peremennaya zvezda RS Lebedya dostignet maksimuma bleska (6m). Krome etogo, vsyu nedelyu na fone vechernih i utrennih sumerek vozmozhno poyavlenie serebristyh oblakov, a takzhe nevooruzhennym glazom vidna yarkaya

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 20 minut. Vidimyi diametr Solnca uvelichivaetsya do 31,49 minut dugi, a dvizhetsya ono po sozvezdiyu Bliznecov. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 20 iyulya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Bliznecov, Raka, L'va, Devy, izmenyaya fazu ot 0,0 do 0,45+ i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Bliznecov. Posle novoluniya Luna pereidet na vechernee nebo, a 21 iyulya molodoi mesyac budet nablyudat'sya v sozvezdii Raka okolo zvezdnogo skopleniya Yasli (M44). 22 iyulya rastushii lunnyi serp pereidet v sozvezdie L'va, gde v etot den' proidet severnee Regula. Prodolzhaya uvelichivat' fazu, Luna pereidet v sozvezdie Devy 24 iyulya, sovershiv po nemu trehdnevnoe puteshestvie, proidya severnee Spiki 26 iyulya. Fazy Luny na dannoe vremya i na budushee.

Iz planet Solnechnoi sistemy (utrennii parad planet): Merkurii viden na fone utrennei zari, Venera imeet utrennyuyu vidimost', a Mars, Uran i Neptun mozhno nablyudat' noch'yu i utrom. Yupiter i Saturn nablyudayutsya vsyu noch'. Podrobnye efemeridy i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii AK_2020 na http://www.astronet.ru/db/msg/1364099 . Efemeridy Solnca, Luny i planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ .

Iz komet hvostataya strannica NEOWISE (C/2020 F3) vidna na fone sumerechnogo segmenta v sozvezdii Bol'shoi Medvedicy s bleskom okolo +2m. Kometa PANSTARRS (C/2017 T2) pri bleske okolo 9m dvizhetsya po sozvezdiyu Volos Veroniki, a kometa Enke pri bleske slabee 8m peremeshaetsya po sozvezdiyam Sekstanta i Chashi. Karty putei komet i asteroidov na mesyac imeyutsya v KN na iyul', a na drugie periody - v Astronomicheskom kalendare na 2020 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 na dannoi nedele budut: Vesta (8,2m) v sozvezdii Bliznecov i Cerera (8,2m) v sozvezdii Vodoleya.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: S Malogo L'va 8,6m - 21 iyulya, T Zhuravlya 8,6m - 21 iyulya, R Treugol'nika 6,2m - 22 iyulya, T Cefeya 6,0m - 22 iyulya, R Vodoleya 6,5m - 22 iyulya, W Liry 7,9m - 23 iyulya, RU Gidry 8,4m - 24 iyulya, V Zmeenosca 7,5m - 24 iyulya, S Del'fina 8,8m - 24 iyulya, RS Lebedya 7,2m - 25 iyulya.

Nekotorye blizkie pary svetil: Luna - Yasli (M44), Luna - Regul, Luna - Spika, Venera - Al'deberan, Yupiter - Saturn, Uran - al'fa Ovna, Neptun - fi Vodoleya.
