DKIST unveils MHD-predicted sub-50 km photospheric vortices
S. Vargas Dominguez, O. A. Calvo Rebellon, J. S. Castellanos Duran +4
Solar vortices are rotating plasma structures that play a key role in the transport of energy and magnetic helicity from the photosphere to the chromosphere and corona. While numer…
Variability in low Mars atmosphere's HO concentration stimulated by solar cycle activity
Johan Nicolás Molina Córdoba, S. Vargas Domínguez, J. I. Zuluaga
Mars' thin, CO-rich atmosphere poses a unique puzzle involving composition, climate history, and habitability. This work explores the intrincate relationship between Mars' atmo…
Analysis of magnetic polarities in active regions for the prediction of solar flares
N. Granados Hernández, S. Vargas Domínguez
Solar active regions and the processes that occur in them have been extensively studied and analyzed and many types of models and characterizations have been proposed for the occur…
Comparative analysis of sky quality and meteorological variables during the total lunar eclipse on 14-15 April 2014 and their effect on qualitative measurements of the Bortle scale
C. Góez Therán, S. Vargas Domínguez
A total lunar eclipse is plausible to have an influence on the variation of some environmental physical parameters, specifically on the conditions of the sky brightness, humidity a…
Multi-wavelength observations of vortex-like flows in the photosphere using ground-based and space-borne telescopes
J. Palacios, S. Vargas Domínguez, L. A. Balmaceda +2
In this work we follow a series of papers on high-resolution observations of small-scale structures in the solar atmosphere \citep[][Cabello et al., in prep]{Balmaceda2009, Balmace…
The Grand Aurorae Borealis Seen in Colombia in 1859
Freddy Moreno Cárdenas, Sergio Cristancho Sánchez, Santiago Vargas Domínguez
On Thursday, September 1, 1859, the British astronomer Richard Carrington, for the first time ever, observes a spectacular gleam of visible light on the surface of the solar disk,…
