Astronomicheskaya nedelya s 3 po 9 maya 2021 goda30.04.2021 7:01 | Aleksandr Kozlovskii
Na dannoi nedele 3 maya dolgoperiodicheskaya peremennaya zvezda RS Lebedya dostignet maksimuma bleska (6,5m), a Luna (F= 0,5-) proidet yuzhnee Saturna. V etot zhe den' Merkurii proidet yuzhnee Pleyad. 5 maya maksimuma deistviya dostignut eta-Akvaridy (ZHR= 40) iz sozvezdiya Vodoleya, a Luna (F= 0,39-) proidet yuzhnee Yupitera. 6 maya Luna (F= 0,22-) proidet yuzhnee Neptuna, a 9 maya Venera proidet yuzhnee Pleyad. 9 maya dolgoperiodicheskaya peremennaya zvezda V Volopasa dostignet maksimuma bleska (6,5m), a Merkurii budet nahodit'sya severnee Giad. Krome etogo, idet period, kogda yarkie sputniki Yupitera tesno sblizhayutsya i pokryvayutsya drug drugom.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 52 gradusov, a dolgota dnya na toi zhe shirote vozrastaet do 15 chasov 55 minut. Vidimyi diametr Solnca umen'shaetsya do 31,68 minut dugi, a dvizhetsya ono po sozvezdiyu Ovna. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 3 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Kozeroga, Vodoleya i Ryb, izmenyaya fazu ot 0,6- do 0,03- i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Kozeroga, gde zaderzhitsya do 4 maya. V etom sozvezdii Luna primet fazu poslednei chetverti, nahodyas' yuzhnee Saturna. Pri faze 0,41- serp Luny 4 maya voidet v sozvezdie Vodoleya, gde v etot den' proidet (F= 0,39-) yuzhnee Yupitera. 6 maya Luna dostignet Neptuna, yuzhnee kotorogo budet nablyudat'sya pri faze 0,22-. 7 maya tayushii lunnyi serp budet nablyudat'sya v sozvezdii Ryb, v etot zhe den' pereidya v sozvezdie Kita. Zdes' Luna probudet ves' den' 8 maya, a 9 maya eshe raz pereidet v sozvezdie Ryb pri faze 0,07-. Fazy Luny na dannoe vremya i na budushee.
Iz planet Solnechnoi sistemy: Merkurii i Venera vidny na fone vechernei zari, a Mars mozhno nablyudat' po vecheram. Yupiter i Saturn imeyut utrennyuyu vidimost'. Uran ne viden, a Neptun poyavlyaetsya na utrennem sumerechnom nebe.

Iz komet hvostataya strannica ATLAS (C/2020 R4) s bleskom okolo 10m peremeshaetsya po sozvezdiyam Gonchih Psov i Volos Veroniki. Karty putei komet i asteroidov na mesyac imeyutsya v KN na mai, a na drugie periody - v Astronomicheskom kalendare na 2021 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 yarkoi na dannoi nedele budet Vesta (7,1m) v sozvezdii L'va.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: ST Strel'ca 8,3m - 3 maya, RS Lebedya 7,4m - 3 maya, U Maloi Medvedicy 8,2m - 7 maya, V Volopasa 7,8m - 9 maya.
