I-Northern Lights (ebizwa nangokuthi i-Aurora Borealis) ivela lapho inani elikhulu lama-electron, elivela elangeni, lijikeleza ukuya ngaseMhlabeni eduze nensimu yalo magnetic futhi lihlanganiswe nezinhlayiya zomoya. Umoya uqala ngokufana nalokho okwenzekayo ngaphakathi kwe-tube fluorescent, eduze kwamakhilomitha angu-100 ngaphezulu komhlaba. Imibala ephumela eNyakatho Lights ibonisa amagesi esiyithola lapho.
Kuvame ukubona izibani eziluhlaza, nakuba ukukhanya okubomvu okubonakala njengokukhanya kwelanga elimnyama nakho kwesinye isikhathi kubonakala, ikakhulukazi eScandinavia. Izulu elikhanyayo libizwa nangokuthi "polar aurora" nelithi "aurora polaris".
Izimo zesimo sezulu elangeni nasemhlabeni zinquma ukuthi ngabe i-aurora ingabonwa noma cha. Lapho kubonakala, izibani zingabonakala ngamakhilomitha angaba ngu-400 ukusuka ekugcineni, ngenxa yesikhumba somhlaba.
Izindawo Ezinhle Zokubona I-Aurora Borealis
Ukuze ubone lokhu kwenzeka, vakashela indawo ye-auroral (noma iyiphi indawo ngaphesheya kwe- Arctic Circle ) lapho i-Northern Lights ivela khona. Izindawo eziyinhloko yizindawo ezisemadolobheni aseNorway aseTromsø, eNorway (eduze neNyakatho Kapa ), naseReykjavik, e-Iceland, ngisho nasezingeni eliphansi lemisebenzi yokukhanya esenyakatho. Kuzo zonke izindawo ze-Nordic, lezi zindawo zikunikeza ithuba elihle lokubona into evelele.
Ngaphezu kwalokho, kokubili izindawo zinikeza inkathi ende yokubuka, emnyama ngoba ikhona ngaphesheya kwe-Arctic Circle (ikakhulukazi phakathi nobusuku be-polar , uma kungekho ukukhanya kwelanga).
Uma ungafuni ukuya enyakatho enkulu, indawo elandelayo ukubona izibani ezisenyakatho yisifunda phakathi kwedolobha laseFinnish edolobheni laseRuvaniemi kanye nedolobhana laseNorway iBodø, eduze komngcele we-circle arctic.
Kusuka lapha, usakwazi ukubona izibani ezisenyakatho njalo.
Izindawo ezikude eningizimu njenge-Umeå, eSweden, naseTrondheim, eNorway, azizona ezithembekile kodwa zindlela ezihlukile kumuntu ohamba ngezinyawo. Lezi zindawo zidinga izibani ezisenyakatho ezinamandla kakhulu ezisenyakatho ze-geomagnetic ukuze zijabulele isenzakalo semvelo esiseduze, ngakho ngeke uzibone njalo.
I-Northern Lights ingabonwa kwezinye izindawo ezisenyakatho futhi, kodwa ingxenye engasenyakatho yeNorway neSweden, kanye nayo yonke i-Iceland, idume ngokuba ne "izihlalo ezingcono" zokubuka i-Aurora Borealis.
Isikhathi Esihle Sokubona i-Aurora Borealis
Sihlobanisa i-Aurora Borealis ngobusuku obumnyama, obubandayo nabusika, nakuba lesi simo sokwemvelo senzeke ngaso sonke isikhathi (kunzima ukubona emibhathini elula).
Isikhathi esihle sokubona izibani ezisenyakatho ukusuka noma kuphi noma ngaphezulu kwe-Arctic Circle (eseduze kwamadolobha aseRovaniemi, eFinland naseBodø, eNorway) kunoma yisiphi isikhathi phakathi kukaSepthemba nangasekupheleni kuka-Ephreli. Uzothola ubusika obude obusika lapha.
Okuqhubekayo eningizimu eScandinavia uyahamba, isikhathi esifushane se-Aurora Borealis sizoba, ngenxa yokuthi kukhona ukukhanya okukhulu ezinyangeni ngaphambi nangemva kwebusika. Phakathi kuka-Okthoba noMashi yisikhathi esihle sokubona izibani ezisenyakatho kuleyo ndawo.
Isikhathi esihle sebusuku ukukhanya okungenyakatho ngehora lesishiyagalolunye kuya ku-2 ekuseni. Khumbula ukuthi izivakashi eziningi ziphuma ukuze ziqale i-watch yazo zizungeze ngo-10 ntambama bese ziphetha ubusuku bazo cishe ngo-4 ekuseni kusukela ukukhanya okungasenyakatho kungaba nzima ukubikezela (njenge sezulu eScandinavia ).
Uma ungaboni izibani ezisenyakatho njengoba kulindeleke ngisho noma isikhathi siphezulu, abantu bendawo batusa ukuba balinde isikhathi esisodwa kuya emahoreni amabili. Uhlobo luvame ukuvuza isiguli esiphezulu kakhulu.
Kakhulu kangakanani i-Aurora Borealis iyabonakala
Lokhu kuxhomeke endaweni yakho. Endolobheni laseTorso laseTorso (eTromsø) eNorway naseNyakatho Kapa (Nordkapp), ungabona iMigodi yaseNyakatho yonke eminye ubusuku obucacile, uma kungenjalo njalo. Okufanayo kuya ezindaweni ezingaphezulu enyakatho.
Ngaseningizimu (isib. Central / south Sweden), kunzima ukubona i-Aurora Borealis, futhi kungenzeka izikhathi ezingu-2-3 ngenyanga kuphela.
Indlela Yokudweba I-Aurora Borealis
Kungenzeka usuvele unayo imishini yokuthatha izithombe oyidingayo. Thola ukuthi ungayithatha kanjani isithombe seNyakatho Lemibala .
Indlela Yokuchaza Ngamathuba Okuthi Izibani ZaseNyakatho Zindawo Eqondile
Ukubikezela izibani ezisenyakatho, udinga ukwazi indawo ozoyibuka khona. Ukubikezela kwezibani ezisenyakatho kulinganisa umsebenzi wokulinda we-geomagnetic ku-okuthiwa i-Kp index (1 kuya ku-10).
Nazi ezinye amathiphu okuzokusiza ukubikezela:
- Hlola izinsuku zakho zokuhamba kwi-Outlook esemthethweni ye-NOAA Space Weather Outlook, ehlala ibikezelwe izinsuku ezingu-27 ezilandelayo.
- Thola inombolo ye-Kp ebalwe usuku othanda ngalo. Inani eliphakeme le-Kp ekubikezelweni liwukuthi, ezansi ngeningizimu izibani ezisenyakatho zizobonakala.
- Qhathanisa inombolo oyitholayo nendawo yakho ukucacisa ukuthi ngabe izibani zaseNyakatho zizobonakala yini:
- Izibikezelo zezibani zaseNyakatho zezindawo ezifana ne-Tromsø neReykjavik zibonisa izibani ezisenyakatho ekugcineni ngisho nase-0 Kp kusukela ekwindla kuze kufike entwasahlobo. Okungenani u-1 kuya ku-2 Kp (nangaphezulu) kuzoqinisekisa ukuthi izibani ezisenyakatho ziphezulu ngokuqondile kulezi zindawo.
- I-Rovaniemi, eFinland, idinga kuphela inkomba ye-Kp ye-1 ukuze kubonakale izibani ezisenyakatho enyakatho.
- Njengasekugcineni eningizimu njenge-Umeå ne-Trondheim, uzodinga okungenani u-2 Kp ukubikezela ukubona izibani ekugcineni, noma inani le-Kp le-4 ukuze lijabulele ngaphezulu.
- Futhi uma uhlezi ezindaweni ezizungezile izihloko ezinkulu zaseScandinavia i-Oslo, i-Stockholm ne-Helsinki, inkomba ye-Kp kufanele ibe okungenani engu-4 ekukhanyeni okukhanyayo okukhanyayo enyakatho noma 6 ukuze izibani ezisenyakatho zenzeke ngokuqondile.
- Uma kuqhathaniswa, iYurophu ephakathi idinga 8 kuya ku-9 Kp (umsebenzi ophezulu kakhulu we-auroral) ukubona izibani ezisenyakatho nhlobo.
Khumbula: Nakuba umsebenzi ubikezelwa unyaka wonke, izibani ezisenyakatho ngokuvamile azikwazi ukubonakala Ngangonyaka ka-Septhemba. Ukubonakala kwezibani ezisenyakatho nakho kuxhomeke ezimweni zendawo zesimo sezulu. Isembozo sefu sizofihla izibani ezisenyakatho ngisho noma ukubikezelwa kubonisa ukuthi kungenzeka ukuthi kwenzeke.
