Na dannoi nedele 2 marta proizoidet pokrytie Lunoi (F= 0,47+) zvezdy epsilon Tel'ca (3,5m) pri vidimosti na yuge Sibiri i v Primor'e. V etot zhe den' Luna (F= 0,48+) proidet severnee Al'debarana, a 4 marta proizoidet pokrytie Lunoi (F= 0,67+) zvezdy eta Bliznecov (3,3m) pri vidimosti v Sibiri i na Dal'nem Vostoke. V etot zhe den' Luna (F= 0,68+) okazhetsya v voshodyashem uzle svoei orbity, a dolgoperiodicheskaya peremennaya zvezda RV Strel'ca dostignet maksimuma bleska (6,5m). 5 marta dolgoperiodicheskaya peremennaya zvezda R Bliznecov dostignet maksimuma bleska (6m), a Luna (F= 0,72+) proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora. 6 marta Luna (F= 0,88+) proidet severnee zvezdnogo skopleniya Yasli (M44), a 8 marta pri faze 0,97+ - severnee Regula. V etot zhe den' Neptun dostignet soedineniya s Solncem, a Venera proidet v 2 gradusah severnee Urana.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 30 gradusov, a dolgota dnya na toi zhe shirote - do 11 chasov 15 minut.
