DOIRAI RUYHATI HARITAI OSMONI SITORAZOR

Badi sahekh muayyan kardani koordinatahoi a va 8-i sitoraho kharitai gardandai osmoni sitorazor, ki ba shakli pahnkarda- shudai kharitai jugrofy monand ast, sokhta meshavad (nigared ba doirahoi kharitagy). Dar girdogirdi kharitai sitoraho mohho, ruzho va soatkhoe, ki jamojam yak shabonaruzro (24 soat) tashkil medikhand, kayd gardidaast (rasmi 5.2.9, b). Dar satkhi kanorii kursi (diski) bekharakat adadkhoi shabonaruzy (24 soat) takroran kayd meshavad (rasmi 5.2.9, a). Kame durtar az markazi charkhzanii in kurs, ki az on tiri dunyo meguzarad, khalkai kushodai ellipsmonandi ba arzi jugrofii makhal muvofik kardashudaro mebined, ki dar atrofi on adadkhoi darajagii arzi makhalro darbargiranda navishta shudaand.

Baroi yoftani in yo on burj yo sitora, muvofiq ba vaqti makhal (1 soat, 2 soat,… 24 soat) kursro bo angushton ba kharakat darovarda, vakti makhalro (masalan, soati 20-ro) ba boloi soati 20-i khamon ruzi mushokhida (masalan, 22 sentyabr), ki dar satkhi bekharakti kharita navishta shudaast, meguzorem.

Dar in kholat dar dokhili khalkai ellipsmonand sitorakho va burjkhoi khamin ruzro (22 sentyabr, soati 20) didan mumkin ast.
