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…
A Great Space Weather Event in February 1730
Hisashi Hayakawa, Yusuke Ebihara, José M. Vaquero +9
Aims. Historical records provide evidence of extreme magnetic storms with equatorward auroral extensions before the epoch of systematic magnetic observations. One significant magne…
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…
