The Spanish Space Weather Service SeNMEs. A case study on the Sun-Earth chain
J. Palacios, C. Cid, A. Guerrero +6
The Spanish Space Weather Service SeNMEs, \url{www.senmes.es}, is a portal created by the SRG-SW of the Universidad de Alcalá, Spain, to meet societal needs of near real-time spac…
Modeling the recovery phase of extreme geomagnetic storms
C. Cid, J. Palacios, E. Saiz +3
The recovery phase of the largest storms ever recorded has been studied. These events provide an extraordinary opportunity for two goals: (1) to validate the hyperbolic model by Ag…
Flux emergence event underneath a filament
J. Palacios, Y. Cerrato, C. Cid +2
Flux emergence phenomena are relevant at different temporal and spatial scales. We have studied a flux emergence region underneath a filament. This filament elevated itself smoothl…
A Hyperbolic Decay of the Dst Index during the Recovery Phase of Intense Geomagnetic Storms
J. Aguado, C. Cid, E. Saiz +1
What one commonly considers for reproducing the recovery phase of magnetosphere, as seen by the Dst index, is exponential function. However, the magnetosphere recovers faster in th…
Linking two consecutive nonmerging magnetic clouds with their solar sources
S. Dasso, C. H. Mandrini, B. Schmieder +10
On 15 May 2005, a huge interplanetary coronal mass ejection (ICME) was observed near Earth. It triggered one of the most intense geomagnetic storms of solar cycle 23 (Dst peak = -2…
Solar sources of the geoeffective events in September 2011
J. Palacios, A. Guerrero, C. Cid +2
We investigate the geoeffective events happened from 8 to 20 Sept 2011, analysing the most plausible solar sources of these events, where coronal mass ejections and coronal holes p…
