Soonspot: Software to Determine Areas and Sunspot Positions
P. Galaviz, V. M. S. Carrasco, F. Sánchez-Bajo +2
A new software (Soonspot) for the determination of the heliographic coordinates and areas of sunspots from solar images is presented. This program is very user-friendly and the acc…
Sunspot characteristics at the onset of the Maunder Minimum based on the observations of Hevelius
V. M. S. Carrasco, J. M. Vaquero, M. C. Gallego +8
An analysis of the sunspot observations made by Hevelius during 1642-1645 is presented. These records are the only systematic sunspot observations just before the Maunder Minimum.…
A Normalized Sunspot-Area Series Starting in 1832: an Update
V. M. S. Carrasco, J. M. Vaquero, M. C. Gallego +1
A new normalized sunspot-area series has been reconstructed from the series obtained by the Royal Greenwich Observatory and other contemporary institutions for the period 1874 - 20…
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…
