22.05.2015 17:26 | Aleksandr Kozlovskii
Na dannoi nedele Merkurii proidet v polutora gradusah yuzhnee Marsa i dostignet nizhnego soedineniya s Solncem. Krome etogo, kometa Lavdzhoya sblizitsya s Polyarnoi zvezdoi do gradusa, a peremennaya zvezda V Gonchih Psov budet dostupna nevooruzhennomu glazu. 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, 27 maya Ganimed pokroet Evropu i Io. Podrobnaya tablica soedinenii. Konfiguracii sputnikov mozhno utochnit' po grafiku v KN na mai.
Iz planet Solnechnoi sistemy: Merkurii i Mars ne vidny, Venera i Yupiter nablyudayutsya ves' vecher, Saturn dostupen dlya nablyudenii vsyu noch', a Uran i Neptun mozhno obnaruzhit' v binokl' ili teleskop v utrennie chasy.
Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya L'va, Devy i Vesov, obladaya vechernei i nochnoi vidimost'yu. Nachalo nedeli nochnoe svetilo provedet v sozvezdii L'va. Zdes' Luna sblizitsya s Regulom (prinyav fazu pervoi chetverti), a 26 maya pereidet v sozvezdie Sekstanta, zaderzhavshis' v nem na poldnya. Vtoruyu polovinu sozvezdiya L'va Luna proidet za odin den' i vecherom 27 maya pereidet v sozvezdie Devy, uvelichiv fazu do 0,66. K koncu dnya 29 maya yarkii lunnyi oval vtoroi raz za mesyac proidet severnee Spiki pri faze 0,86, a pod utro 31 maya pereidet v sozvezdie Vesov. Zdes' (bliz zvezdy al'fa Vesov) Luna zakonchit svoi put' po vesennemu nebu, nablyudayas' vsyu noch' v vide pochti polnogo lunnogo diska (F= 0,97).
Iz komet vysokim bleskom (okolo 8m) obladaet C/2014 Q2 ( Lovejoy ), kotoraya nahoditsya okolo Polyarnoi zvezdy v sozvezdii Cefeya i Maloi Medvedicy. Kometa 88P/Howell vidna po utram v sozvezdii Kita. 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 otnositel'no yarkih (do 8,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: U CET (7,5m) - 25 maya, V CVN (6,8m) - 28 maya.
Iz osnovnyh meteornyh potokov aktivny eta-Akvaridy.
Nekotorye pary svetil, popadayushie v pole zreniya binoklya na dannoi nedele: Luna - Regul, Luna - Spika, Merkurii - Mars, Merkurii - Giady, Saturn - beta Skorpiona, Uran - dzeta Ryb, Neptun - sigma Vodoleya, C/2014 Q2 (Lovejoy) - Polyarnaya zvezda.

Na etoi nedele Luna ne sblizitsya ni s odnoi planetoi.
Merkurii. Planeta peremeshaetsya popyatno po sozvezdiyu Tel'ca (severnee Giad). Merkurii skryvaetsya v luchah zahodyashego Solnca, a na utrennem nebe poyavitsya v konce iyunya. V konce nedeli on proidet nizhnee soedinenie s Solncem i sblizitsya s Zemlei do minimal'nogo rasstoyaniya. Blesk planety umen'shaetsya ot 4,0m do 5,4m, vidimyi diametr postepenno vozrastaet ot 11,8 do 12,2 uglovyh sekund, a faza imeet znachenie okolo 0. Rasstoyanie ot Zemli umen'shaetsya ot 0,57 do 0,55 a.e.. Kosmicheskie issledovaniya - Messendzher.
Venera. Planeta obladaet pryamym dvizheniem v sozvezdii Bliznecov bliz ego samyh yarkih zvezd (Kastor i Polluks). Vechernyaya Zvezda yavlyaetsya ukrasheniem sumerechnogo i rannego nochnogo neba. V teleskop viden nebol'shoi belyi poludisk 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 45,3 gradusa, a uglovye razmery planety - ot 20,5 do 22,0 sekund dugi. Blesk sohranyaetsya na urovne -4,2m pri faze, umen'shayusheisya ot 0,57 do 0,53. Rasstoyanie mezhdu Zemlei i Veneroi umen'shaetsya ot 0,81 do 0,76 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 2,54 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 35,3 do 34,6 sekund dugi (-1,9m), a rasstoyanie ot Zemli uvelichivaetsya ot 5,58 do 5,68 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 nahoditsya bliz protivostoyaniya s Solncem, 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. Planeta (m= +6,0, d= 3,3 ugl. sek.) dvizhetsya v odnom napravlenii s Solncem v sozvezdii Ryb (u granicy s sozvezdiem Kita) bliz zvezdy dzeta Psc (5,2m). 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 20,70 do 20,62 a.e.. Kosmicheskie issledovaniya - Voyadzher-2.
Neptun. Planeta (m= +8,0, d= 2,3 ugl. sek.) peremeshaetsya v odnom napravlenii s Solncem po sozvezdiyu Vodoleya mezhdu zvezdami sigma Aqr (4,8m) i lyambda Aqr (3,7m). 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 30,06 do 29,94 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 32,04 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).
