Evidence for a White-light Flare on 10 September 1886
J. M. Vaquero, M. Vázquez, J. Sánchez Almeida
We present evidence for the occurrence of a white-light flare on 10 September 1886. It represents the third of such rare events reported in the history of astronomy. The flare was…
Long-term Spatial and Temporal Variations of Aurora Borealis Events in the Period 1700--1905
M. Vázquez, J. M. Vaquero, M. C. Gallego
Catalogues and other records of aurora-borealis events were used to study the long-term spatial and temporal variation of these phenomena in the period from 1700 to 1905 in the Nor…
Time series of high resolution photospheric spectra in a quiet region of the Sun. II. Analysis of the variation of physical quantities of granular structures
K. G. Puschmann, B. Ruiz Cobo, M. Vazquez +2
From the inversion of a time series of high resolution slit spectrograms obtained from the quiet sun, the spatial and temporal distribution of the thermodynamical quantities and th…
Time series of high resolution photospheric spectra in a quiet region of the Sun. I. Analysis of global and spatial variations of line parameters
K. G. Puschmann, M. Vazquez, J. A. Bonet +2
A 50 min time series of one-dimensional slit-spectrograms, taken in quiet sun at disk center, observed at the German Vacuum Tower Telescope (Observatorio del Teide), was used to st…
