Ọrụ Anyanwụ: Onye A Na-anaghị Ahụ Anya Mere Ya

Nnyocha NASA na-akwado njikọ kpọmkwem n'etiti mwepụta satịlaịtị na usoro anyanwụ. Mmalite nke afọ 2019 dakọtara na obere ike anyanwụ, mana ka ọrụ anyanwụ na-akawanye njọ, ndọda ikuku na orbit 340-550km mụbara site na >50% n'oge oké ifufe geomagnetic. Nke a na-eme mgbe:

1. Mgbawa anyanwụ/mgbawa coronal nke anyanwụ na-akpata na-awakpo ụwa
2. Oké ifufe Geomagnetic na-ekpo ọkụ ma na-agbasa ikuku elu
3. Ikuku gbasaara na-eme ka ndọkpụ na-arị elu, na-akpata ire ere gburugburu

Ihe mgbagwoju anya: Oké ifufe na-adịghị ike na-egbu egbu karịa

N'adịghị ka a tụrụ anya ya, pasentị iri asaa nke mfu mere n'oge oké ifufe geomagnetic dị obere/adịghị ike.
