Astronomicheskaya nedelya s 13 po 19 iyulya 2020 goda22.06.2020 7:10 | Aleksandr Kozlovskii
Na dannoi nedele 14 iyulya Yupiter vstupit v protivostoyanie s Solncem. V etot zhe den' Luna (F= 0,35-) proidet yuzhnee Urana, a dolgoperiodicheskaya peremennaya zvezda R Raka dostignet maksimuma bleska (6m). 16 iyulya Luna (F= 0,22-) proidet yuzhnee Pleyad, a takzhe proizoidet pokrytie Lunoi (F= 0,15-) zvezdy epsilon Tel'ca (3,5m) pri vidimosti v vostochnoi polovine strany. V etot zhe den' asteroid Pallada (9,6m) vstupit v protivostoyanie s Solncem. 17 iyulya Luna (F= 0,15-) proidet severnee Venery i Al'debarana. 18 iyulya Luna (F= 0,06-) okazhetsya v voshodyashem uzle svoei orbity, a 19 iyulya pri faze 0,03- proidet severnee Merkuriya bliz tochki maksimal'nogo skloneniya k severu ot nebesnogo ekvatora. Vsyu nedelyu imeet mesto parad planet, kogda vse bol'shie planety Solnechnoi sistemy mozhno nablyudat' na utrennem nebe. Na fone utrennei zari viden Merkurii, a znachitel'no pravee ego - Venera. Eshe pravee v binokl' mozhno nablyudat' Uran. Dalee k zapadu viden krasnovatyi Mars, a pravee ego v binokl' ili teleskop mozhno otyskat' Neptun. Saturn i Yupiter nablyudayutsya eshe pravee u yugo-zapadnogo gorizonta. Krome etogo, vsyu nedelyu na fone vechernih i utrennih sumerek vozmozhno poyavlenie serebristyh oblakov, a levee yarkoi zvezdy Kapella iz sozvezdiya Voznichego nablyudaetsya yarkaya kometa NEOWISE (C/2020 F3) s bleskom okolo 2m. V srednih shirotah kometa yavlyaetsya uzhe nezahodyashei. Utrom nebesnaya strannica vidna vo vsem velikolepii nevooruzhennym glazom. Vyplyvaet iz serebristyh oblakov, nevol'no podskazyvaya sravnenie "Beleet (zhelteet) parus odinokii v tumane morya golubom" Parus (hvost), konechno, krohotnyi (nevooruzhennym glazom), no v binokl' - velikolepnoe zrelishe. Blesk 2 zvezdnye velichiny. Voshodyashaya Venera yavlyaetsya nekim orientirom po usloviyam vidimosti komety. Luchshe vsego nebesnaya gost'ya vidna do voshoda utrennei zvezdy, a posle ee poyavleniya u gorizonta vidimost' komety nachinaet uhudshat'sya, t.k. nebo stanovitsya vse svetlee. No nevooruzhennym glazom kometu vidno eshe minimum polchasa posle voshoda Venery. Eti usloviya, konechno, spravedlivy dlya srednih shirot Kak vidno iz karty, kometa poka uvelichivaet sklonenie i podnimaetsya vse severnee, chto, bezuslovno, uluchshaet ee vidimost' s territorii nashei strany. Kstati, est' horoshii shans pronablyudat' kometu v nizhnei kul'minacii, chto udavalos' nemnogim nablyudatelyam takoi yarkoi komety. I eshe odno zamechatel'noe sovpadenie Kometa vidna kak raz vo vremya utrennego parada vseh planet Solnechnoi sistemy. V obshem, parad planet+. Nablyudaite!
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy sostavlyaet okolo 55 gradusov, a dolgota dnya na toi zhe shirote - 16 chasov 40 minut. Vidimyi diametr Solnca imeet znachenie 31,47 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 Ryb, Ovna, Tel'ca i Bliznecov, izmenyaya fazu ot 0,5- do 0,0 i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Ryb, nablyudayas' na utrennem nebe v yuzhnoi chasti neba. 13 iyulya Luna eshe raz posetit sozvezdie Kita, pereidya 14 iyulya v sozvezdie Ovna (proidya yuzhnee Urana pri faze okolo 0,35-), gde probudet do 15 iyulya, pereidya v etot den' v sozvezdie Tel'ca. V etom sozvezdii 16 iyulya staryi mesyac budet nablyudat'sya na fone utrennei zari yuzhnee Pleyad, dostignuv v etot zhe den' Giad i Al'debarana. 17 iyulya Luna proidet severnee Venery, a zatem ustremitsya k sozvezdiyu Bliznecov, v kotoroe voidet 18 iyulya. Zdes' 19 iyulya lunnyi serp proidet severnee Merkuriya, a 20 iyulya primet fazu novoluniya. 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.
