The Extreme Space Weather Event in February/March 1941
Hisashi Hayakawa, Sean P. Blake, Ankush Bhaskar +3
Given the infrequency of extreme geomagnetic storms, it is significant to note the concentration of three extreme geomagnetic storms in 1941, whose intensities ranked fourth, twelf…
Low-Latitude Aurorae during the Extreme Space Weather Events in 1859
Hisashi Hayakawa, Yusuke Ebihara, David P. Hand +4
The Carrington storm (September 1/2, 1859) is one of the largest magnetic storms ever observed and it has caused global auroral displays in low-latitude areas, together with a seri…
Sporadic Aurora near Geomagnetic Equator: In the Philippines, on 27 October 1856
Hisashi Hayakawa, José. M. Vaquero, Yusuke Ebihara
While low latitude auroral displays are normally considered to be a manifestation of magnetic storms of considerable size, Silverman (2003, JGR, 108, A4) reported numerous "sporadi…
The Great Space Weather Event during February 1872 Recorded in East Asia
Hisashi Hayakawa, Yusuke Ebihara, David M. Willis +9
The study of historical great geomagnetic storms is crucial for assessing the possible risks to the technological infrastructure of a modern society, caused by extreme space-weathe…
Dayside magnetospheric and ionospheric responses to a foreshock transient on June 25, 2008: 2. 2-D evolution based on dayside auroral imaging
Boyi Wang, Yukitoshi Nishimura, Heli Hietala +8
The foreshock region involves localized and transient structures such as foreshock cavities and hot flow anomalies due to solar wind-bow shock interactions, and foreshock transient…
Defining and resolving current systems in geospace
N. Y. Ganushkina, M. W. Liemohn, S. Dubyagin +15
Electric currents flowing through near-Earth space ( 12 ) can support a highly distorted magnetic field topology, changing particle drift paths an…
