Featuring dark coronal structures: physical signatures of filaments and coronal holes for automated recognition

Judith Palacios, Consuelo Cid, Elena Saiz +2

Filaments may be mistaken for coronal holes when observed in extreme ultraviolet (EUV) images; however, a closer and more careful look reveals that their photometric properties are…

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 space…

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…

Searching for Carrington-like events and their signatures and triggers

Elena Saiz, Antonio Guerrero, Consuelo Cid +2

The Carrington storm in 1859 is considered to be the major geomagnetic disturbance related to solar activity. In a recent paper, Cid et al. (2015) discovered a geomagnetic disturba…

Supergranular-scale magnetic flux emergence beneath an unstable filament

J. Palacios, C. Cid, A. Guerrero +2

Here we report evidence of a large solar filament eruption on 2013, September 29. This smooth eruption, which passed without any previous flare, formed after a two-ribbon flare and…

A Carrington-like geomagnetic storm observed in the 21st century

C. Cid, E. Saiz, A. Guerrero +2

In September 1859 the Colaba observatory measured the most extreme geomagnetic disturbance ever recorded at low latitudes related to solar activity: the Carrington storm. This pape…

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…

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…

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…

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…
