Bu çalışma, 24. güneş döngüsünde meydana gelen 01 Şubat 2017 (DsT -45 nT) zayıf jeomanyetik fırtınasının matematiksel analizini amaçlamaktadır. NASA'dan alınan güneş rüzgarı parametreleri (Bz, E, P, N, v, T), zonal jeomanyetik indeksleri (Dst, ap, AE) ve neden-sonuç ilişkisini göz önünde bulundurarak Şubat fırtınasının matematiksel modeli ortaya çıkarılmıştır. Makalede fırtına titizlikle analiz edilir ve nedensellik ilkesinin yönettiği modellerle özellikleri ortaya çıkarılmaya çalışılır. Bu çalışmada değişkenlerin değer aralığı ve standart sapmaları tanımlayıcı analiz ile tanımlanır, verilerin binary ilişkileri kovaryans matrisi ile gösterilir ve yine verilerin hiyerarşik kümeleri dendrogram ile tanıtılır. Faktör analizi, verilerin normal dağılımları yardımıyla gerçekleştirilir ve fenomenin gizemi lineer-nonlineer modellerle tartışılmaya çalışılır. Değişkenlerin ikili görünümleri grafikler ile okuyucuya sunularak fırtınaya görsellik kazandırılır. Bu çalışma, literatürde sınırlı sayıda çalışma bulunan zayıf seviyede manyetik fırtınanın modellenmesi konusuna katkı sağlamaktadır.
