Abubuwan Taurari na watan: yadda ake kallon su
Haɗuwa, hamayya, kwadratura da magudanar meteor — menene waɗannan abubuwa, yaushe suke aukuwa kuma menene ainihin za a iya gani ba tare da hangen nesa ba.
Shafin abubuwan taurari na wata yana kama da jerin ranaku da kalmomi waɗanda sauƙi a ɗaukar su a matsayin lissafin ofis. A gaskiya, kusan duk waɗannan ana iya ganinsu ba tare da telescope ba, idan kun san inda za ku duba.
Menene abin taurari
Abu kuwa shi ne — lokacin da matsayin jikin sama tare ya ɗauki yanayi na musamman. Ana ƙaddara shi da bambancin tsawon longitude na ecliptic, don haka duk kusurwoyi a irin waɗannan jerin ana aunawa da digiri a gefen ecliptic.
Manyan nau'ikan
Haɗi — jikin suna da longitude masu kusa kuma suna bayyana a gefen juna. Shi ne mafi fitaccen abu ga mai kallo da ido, sai dai idan Rana ba ta kusa ba: haɗin Merkuri da Rana ba a ganinsa, amma haɗin Jupiter da Saturn — kyakkyawan hoto ne.
Adawa — jikin suna a gefe biyu na sararin sama, bambancin longitude kusan 180°. Duniya mai adawa ana ganinta har tsawon dare, tana fitowa a faduwar rana kuma tana faɗuwa a wayewar gari. Mafi kyawun lokacin kallo a shekara.
Kusurwa mai digiri 90 — bambancin longitude kusan 90°. Duniya ana ganinta galibi da dare, amma ba duka ba: tana fitowa kusan tsakar dare kuma tana faɗuwa kusan tsakar rana.
Ruwancen meteor — ba abin matsayi ba ne, sai dai da yawa daga cikin meteor a cikin ɗan gajeren lokaci. Koli an daidaita shi da aiki; a latitude ɗinmu a tsayi sama da 55° radiator yawanci ba a ganinsa sosai saboda atmosphere.
Abin da ake gani da ido tsirara
Da ido tsirara ake ganin: matsayin taurari, ƙaƙƙanfar meteors, hoton wata, fitowar da faduwar dukkan taurari masu haske, da ciwon sauri a sararin sama mai duhu. Ba a ganin: tauraron ɗan adam, zoban Saturn, cikakkun siffo na faifan Rana, da mafi yawan galaksi masu nisa.
Yadda ake amfani da bayanai
Kowane abu a cikin tebur yana ƙunshe da kwanan wata, lokaci, nisar kusurwa da kuma — abin da ya fi amfani a aikace — azimuth da tsawo na garinku a lokacin aukuwar. Nemo wuri a sararin sama da wannan tsawo a wannan alƙibli: taron kusan tabbas zai kasance a tsakanin digiri goma daga wurin, wato a cikin filin gani ba tare da wani telescope ba.
Abubuwan da suka danganta
Menene tsawoƙin ecliptic na taurari
Ana auna matsayin taurara a sararin sama da tsawoƙin ecliptic — kusurwa tare da jirgin tafiyar Duniya. Muna bayyana yadda ake karanta waɗannan bayanan, menene motsi madaidaici da komawa baya kuma me yasa ganuwa ke dogara da fadin.
Motsi mai koma baya na taurari: me yake faruwa da me yake ba
Motsi mai koma baya — shine lokacin da taurari tana binsa cewa tana motsa baya. Mun bayyana yadda ya ke faruwa, wa ya ke kan shi a haliya da yadda "Motsi mai koma baya na Merkuri" ya ke rage makon makon wato shawara, ba watanni.
