New Insight on the Increasing Seismicity during Tenerife's 2004 Volcanic Reactivation
I. Domínguez Cerdeña, C. del Fresno, L. Rivera
Starting in April 2004, unusual seismic activity was observed in the interior of the island of Tenerife (Canary Islands, Spain) with much evidence pointing to a reawakening of volc…
The Evershed effect observed with 0.2 arsec angular resolution
J. Sanchez Almeida, I. Marquez, J. A. Bonet +1
We present an analysis of the Evershed effect observed with a resolution of 0.2 arcsec. Using the new Swedish 1-m Solar Telescope and its Littrow spectrograph, we scan a significan…
Quiet Sun magnetic fields from simultaneous inversions of visible and infrared spectropolarimetric observations
Itahiza Dominguez Cerdena, Jorge Sanchez Almeida, Franz Kneer
We study the quiet Sun magnetic fields using spectropolarimetric observations of the infrared and visible Fe I lines at 6301.5, 6302.5, 15648 and 15653 A. Magnetic field strengths…
The distribution of Quiet Sun magnetic field strengths from 0 to 1800 G
I. Dominguez Cerdena, J. Sanchez Almeida, F. Kneer
The quiet Sun photospheric plasma has a variety of magnetic field strengths going from zero to 1800 G. The empirical characterization of these field strengths requires a probabilit…
Simultaneous visible and infrared spectro-polarimetry of a solar internetwork region
J. Sanchez Almeida, I. Dominguez Cerdena, F. Kneer
We present the first simultaneous infrared (IR) and visible spectro-polarimetric observations of a solar internetwork region. The Fe I lines at 6301.6 A, 6302.5 A, 15648 A, and 156…
Inter-Network magnetic fields observed with sub-arcsec resolution
I. Dominguez Cerdena, J. Sanchez Almeida, F. Kneer
We analyze a time sequence of Inter-Network (IN) magnetograms observed at the solar disk center. Speckle reconstruction techniques provide a good spatial resolution (0.5" cutoff fr…
