Astronomicheskaya nedelya s 11 po 17 maya 2020 goda2.04.2020 7:01 | Aleksandr Kozlovskii
Na dannoi nedele 11 maya Luna (F= 0,82-) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora, a takzhe proizoidet pokrytie Lunoi (F= 0,77-) zvezdy hi1 Strel'ca (5,0m) pri vidimosti v Sibiri. V etot zhe den' Saturn proidet stoyanie s perehodom k popyatnomu dvizheniyu. 12 maya dolgoperiodicheskaya peremennaya zvezda R Devy dostignet maksimuma bleska (6m), a Luna (F= 0,7-) proidet bliz Yupitera i Saturna. 13 maya Venera proidet tochku stoyaniya s perehodom ot pryamogo k popyatnomu dvizheniyu, a 14 maya dolgoperiodicheskaya peremennaya zvezda RU Gerkulesa dostignet maksimuma bleska (7m). V etot zhe den' Yupiter okazhetsya v stoyanii s perehodom ot pryamogo k popyatnomu dvizheniyu. 15 maya Luna (F= 0,45-) proidet bliz Marsa, a dolgoperiodicheskaya peremennaya zvezda R Malogo L'va dostignet maksimuma bleska (6m). 16 maya Luna (F= 0,31-) proidet bliz Neptuna.

Ne smotrya na nizkoe polozhenie nad gorizontom, oval Luny budet zamechatel'no smotret'sya okolo etih planet Solnechnoi sistemy. 12 maya Luna pereidet v sozvezdie Kozeroga i zaderzhitsya v nem do 14 maya, kogda pereidet v sozvezdie Vodoleya. 14 maya Luna primet fazu poslednei chetverti i proidet yuzhnee Marsa. 16 maya serp Luny sblizitsya s Neptunom, a na sleduyushii den' pereidet v sozvezdie Ryb. Fazy Luny na dannoe vremya i na budushee.
