Na dannoi nedele 31 maya Luna (F= 0,73-) sblizitsya s Saturnom. 1 iyunya Mars proidet v 5,3 gr. yuzhnee Polluksa, a Luna (F= 0,6-) proidet yuzhnee Yupitera. 3 iyunya lunnyi serp pri faze 0,43- proidet yuzhnee Neptuna. 5 iyunya dolgoperiodicheskaya peremennaya zvezda S Devy dostignet maksimuma bleska (6,5m), a takzhe proizoidet pokrytie Lunoi (F= 0,18-) zvezdy nyu Ryb (4,4m) pri vidimosti v Sibiri. 6 iyunya dolgoperiodicheskaya peremennaya zvezda R Malogo L'va dostignet maksimuma bleska (7m). Vsyu nedelyu vozmozhno poyavlenie serebristyh oblakov na fone sumerechnogo segmenta. 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 57 gradusov, a dolgota dnya na toi zhe shirote vozrastaet do 17 chasov 20 minut. Vidimyi diametr Solnca umen'shaetsya do 31,52 minut dugi, a dvizhetsya ono po sozvezdiyu Tel'ca. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 2 iyunya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Kozeroga, Vodoleya, Ryb i Ovna, izmenyaya fazu ot 0,75- do 0,1- i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Kozeroga. Zdes' Luna 31 maya proidet (F= 0,73-) yuzhnee Saturna i zakonchit svoi put' po vesennemu nebu pri faze 0,63-. V pervyi den' leta nochnoe svetilo pereidet v sozvezdie Vodoleya, gde proidet yuzhnee Yupitera pri faze 0,6-. 2 iyunya v etom sozvezdii Luna primet fazu poslednei chetverti, a 3 iyunya proidet yuzhnee Neptuna pri faze 0,43-. Sniziv fazu do 0,38- lunnyi serp dostignet sozvezdiya Ryb, a 4 iyunya pri faze 0,32- pereidet v sozvezdie Kita. Zaderzhavshis' zdes' do 5 iyunya i umen'shiv fazu do 0,22-, Luna snova pereidet v sozvezdie Ryb, gde probudet do 6 iyunya. V etot den' tonkii lunnyi serp (F= 0,14-) eshe raz posetit sozvezdie Kita, a pri faze 0,11- pereidet v sozvezdie Ovna. Fazy Luny na dannoe vremya i na budushee.
