A limit for the values of the Dst geomagnetic index
F. J. Acero, J. M. Vaquero, M. C. Gallego +1
The study of the extreme weather space events is important for a technological dependent society. Extreme Value Theory could be decisive to characterize those extreme events in ord…

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…
An Optical Atmospheric Phenomenon Observed in 1670 over the City of Astrakhan Was not a Mid-Latitude Aurora
I. G. Usoskin, G. A. Kovaltsov, L. N. Mishina +2
It has been recently claimed (Zolotova and Ponyavin, Solar Phys., 291, 2869, 2016, ZP16 henceforth) that a mid-latitude optical phenomenon, which took place over the city of Astrak…
Revisiting the prediction of solar activity based on the relationship between the solar maximum amplitude and max-max cycle length
V. M. S. Carrasco, J. M. Vaquero, M. C. Gallego
It is very important to forecast the future solar activity due to its effect on our planet and near space. Here, we employ the new version of the sunspot number index (version 2) t…
Sunspot latitudes during the Maunder Minimum: a machine-readable catalogue from previous studies
J. M. Vaquero, J. M. Nogales, F. Sánchez-Bajo
The Maunder Minimum (1645-1715 approximately) was a period of very low solar activity and a strong hemispheric asymmetry, with most of sunspots in the southern hemisphere. In this…
