15.05.2015 15:55 | Aleksandr Kozlovskii
Na dannoi nedele Merkurii dostignet stoyaniya s perehodom k popyatnomu dvizheniyu i zakonchit vechernyuyu vidimost', a Saturn, naoborot, imeet luchshie usloviya vidimosti v protivostoyanii s Solncem. Krome etogo, proizoidet pokrytie Lunoi (F= 0,01) glavnoi zvezdy sozvezdiya Tel'ca Al'debaran (ne vidno iz-za blizosti k Solncu). Vsyu nedelyu vozmozhno poyavlenie serebristyh oblakov na fone sumerechnogo segmenta.
Prodolzhaetsya period, kogda sputniki Yupitera (pomimo togo, chto pokryvayutsya i zatmevayutsya samoi planetoi i prohodyat pered nei) pokryvayutsya drug drugom. Naprimer, 21 maya Kallisto pokroet Io, i v etot zhe den' Evropa pokroet Io. Podrobnaya tablica soedinenii. Konfiguracii sputnikov mozhno utochnit' po grafiku v KN na mai.
Iz planet Solnechnoi sistemy: Merkurii viden na fone vechernei zari, Venera - ves' vecher, Mars ne viden, Yupiter dostupen dlya nablyudenii bol'shuyu chast' nochi, takzhe kak i Saturn, a Uran i Neptun mozhno obnaruzhit' v binokl' ili teleskop na fone utrennih sumerek.
Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Tel'ca, Bliznecov, Raka i L'va, obladaya vechernei vidimost'yu. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Tel'ca, gde primet fazu novoluniya. Pereidya na vechernee nebo, molodoi mesyac sblizitsya 19 maya s Marsom i Merkuriem, a zatem prodolzhit puteshestvie po Tel'cu do 20 maya, kogda vstupit v sozvezdie Oriona, uvelichiv fazu do 0,1. 21 maya rastushii serp pereidet v sozvezdie Bliznecov, gde zaderzhitsya do 23 maya, krasuyas' na vechernem nebe bliz Venery i eto - samye zrelishnye vechera mesyaca. Pereidya v sozvezdie Raka (F= 0,2), Luna poidet na sblizhenie s Yupiterom, yuzhnee kotorogo proidet 24 maya pri faze 0,34. V etot zhe den' estestvennyi sputnik Zemli vstupit v sozvezdie L'va
Iz komet vysokim bleskom (okolo 8m) obladaet C/2014 Q2 ( Lovejoy ), kotoraya nahoditsya okolo Polyarnoi zvezdy v sozvezdii Cefeya. Kometa 88P/Howell vidna po utram v sozvezdii Ryb. Karty putei komet i asteroidov - v KN na mai.
Sredi asteroidov samyi vysokii blesk (7,8m) imeet Vesta, peremeshayushayasya k vostoku po sozvezdiyu Vodoleya.
Iz osnovnyh meteornyh potokov aktivny eta-Akvaridy.
Nekotorye pary svetil, popadayushie v pole zreniya binoklya na dannoi nedele: Luna - Mars, Luna - Merkurii, Luna - Venera, Luna - Yupiter, Merkurii - Giady, Saturn - beta Skorpiona, Uran - del'ta Ryb, Neptun - sigma Vodoleya, C/2014 Q2 (Lovejoy) - Polyarnaya zvezda.

Na etoi nedele Luna pri faze 0,00 sblizitsya s Marsom, 19 maya pri faze 0,02 - s Merkuriem, 21 maya pri faze 0,15 - s Veneroi, 24 maya pri faze 0,37 - s Yupiterom.
Merkurii. Planeta peremeshaetsya v odnom napravlenii s Solncem po sozvezdiyu Tel'ca (severnee Giad), 19 maya menyaya dvizhenie na popyatnoe. Merkurii eshe mozhno nablyudat' na fone vechernei zari u zapadnogo gorizonta, no vo vtoroi polovine nedeli on skroetsya v luchah zahodyashego Solnca (elongaciya umen'shitsya do 10 gradusov). Tem ne menee, nablyudatelyam predostavlyaetsya vozmozhnost' zafiksirovat' naibolee tonkii serp planety v samom konce vidimosti, kotoryi dlya raznyh shirot opredelyaetsya opytnym putem. Poiski bystroi planety mozhno nachinat' v binokl' posle zahoda Solnca. Blesk planety umen'shaetsya ot 2,1m do 4,0m, vidimyi diametr postepenno vozrastaet ot 10,4 do 11,8 uglovyh sekund, a faza umen'shaetsya ot 0,13 do 0,03. Rasstoyanie ot Zemli umen'shaetsya ot 0,67 do 0,57 a.e.. Kosmicheskie issledovaniya - Messendzher.
Venera. Planeta obladaet pryamym dvizheniem v sozvezdii Bliznecov. Vechernyaya Zvezda yavlyaetsya ukrasheniem sumerechnogo i rannego nochnogo neba. V teleskop viden nebol'shoi belyi oval bez detalei. Opytnye nablyudateli mogut otyskat' Veneru na dnevnom nebe s primeneniem binoklya i nevooruzhennym glazom. Luchshee vremya dlya etogo - vtoraya polovina dnya. Nachinayushim lyubitelyam astronomii takie nablyudeniya nuzhno provodit' v prisutstvii bolee opytnyh nablyudatelei vo izbezhanie napravleniya opticheskogo instrumenta na Solnce, v rezul'tate chego mozhno povredit' zrenie! Elongaciya Venery k koncu nedeli uvelichivaetsya do 44,9 gradusa, a uglovye razmery planety - ot 19,2 do 20,5 sekund dugi. Blesk sohranyaetsya na urovne -4,2m pri faze, umen'shayusheisya ot 0,60 do 0,57. Rasstoyanie mezhdu Zemlei i Veneroi umen'shaetsya ot 0,87 do 0,81 a.e.. Kosmicheskie issledovaniya - Venera-Ekspress.
Mars. Zagadochnaya planeta peremeshaetsya v odnom napravlenii s Solncem po sozvezdiyu Tel'ca, no ne vidna. Blesk Marsa sostavlyaet +1,4m, a vidimyi diametr - okolo 4 sekund dugi. Rasstoyanie mezhdu Marsom i Zemlei v konce nedeli uvelichivaetsya do 2,53 a.e.. Kosmicheskie issledovaniya - MSL Curiosity.
Yupiter. Gazovyi gigant imeet pryamoe dvizhenie, peremeshayas' po sozvezdiyu Raka i priblizhayas' k granice sozvezdiya L'va. Yupiter dostupen dlya nablyudenii bol'shuyu chast' nochi, a viden on na nebe v vide yarkoi zvezdy zheltovatogo cveta nad yuzhnym i yugo-zapadnym gorizontom v vechernee vremya. Uglovoi diametr samoi bol'shoi planety Solnechnoi sistemy umen'shaetsya ot 36,0 do 35,3 sekund dugi (-1,9m), a rasstoyanie ot Zemli uvelichivaetsya ot 5,47 do 5,58 a.e.. Prodolzhaetsya blagopriyatnyi period vidimosti Yupitera. V nebol'shoi teleskop mozhno razglyadet' polosy na diske planety (parallel'no ekvatoru) i drugie detali, a takzhe pokrytiya sputnikov planetoi i prohozhdeniya ih pered planetoi. V lyubitel'skie teleskopy srednei sily nablyudaetsya prohozhdenie tenei sputnikov po poverhnosti samoi bol'shoi planety Solnechnoi sistemy, a takzhe vzaimnye pokrytiya (!!) ee sputnikov. Konfiguracii chetyreh bol'shih sputnikov Yupitera imeyutsya v KN na mai. Kosmicheskie issledovaniya - Galileo.
Saturn. Okol'covannaya planeta peremeshaetsya popyatno po sozvezdiyu Vesov bliz zvezdy beta Sco s bleskom +2,6m. Saturn mozhno nablyudat' bol'shuyu chast' nochi. Planeta priblizhaetsya k svoemu protivostoyaniyu. kotoroe nastupit 23 maya, poetomu blesk ee (0,0m) i uglovoi diametr (18,5 sekund dugi) - maksimal'ny. V teleskop horosho vidno kol'co (dostigayushee v dlinu bolee 40 uglovyh sekund pri naklone k nablyudatelyu pod uglom 24 gradusa) i inogda detali poverhnosti planety, a iz sputnikov naibolee dostupen Titan (8,0m). Rasstoyanie ot Zemli do Saturna priderzhivaetsya znacheniya 8,97 a.e.. Kosmicheskie issledovaniya - Kassini.

Uran poyavlyaetsya na utrennem nebe, i ego mozhno naiti v binokl' na fone utrennih sumerek. Dlya rassmotreniya diska planety ponadobitsya teleskop s uvelicheniem ot 80 krat (pri ideal'nyh usloviyah) i vyshe. Rasstoyanie mezhdu Zemlei i Uranom umen'shaetsya za nedelyu ot 20,78 do 20,70 a.e.. Kosmicheskie issledovaniya - Voyadzher-2.

Neptun nahoditsya na utrennem nebe, a naiti ego mozhno v binokl' ili teleskop. Dlya rassmotreniya diska planety ponadobitsya instrument s uvelicheniem ot 100 krat (pri ideal'nyh usloviyah) i vyshe. Polozhenie samyh dalekih planet na nebesnoi sfere mozhno prosmotret' na zvezdnyh kartah v KN na yanvar' i Astronomicheskom kalendare na 2015 god. Rasstoyanie mezhdu Zemlei i Neptunom umen'shaetsya ot 30,17 do 30,06 a.e.. Kosmicheskie issledovaniya - Voyadzher-2.
Pluton. Karlikovaya planeta ili plutoid (+14m) nahoditsya v sozvezdii Strel'ca (bliz trio zvezd pi, omikron i ksi Sgr) na rasstoyanii 32,11 a.e.. ot Zemli k koncu nedeli. Dlya vizual'nyh nablyudenii Plutona neobhodim teleskop s diametrom ob'ektiva ot 250 mm i prozrachnoe nebo. Kosmicheskie issledovaniya - Novye Gorizonty (14 iyulya 2015 goda maksimal'noe sblizhenie).
