Application of the Markov Chain Model to Sunspots and Solar Plages for the Period 1910 to 1937 Using Data fromEbro Catalogues
(Solar Physics (2021) 296:92, 2021-06-11)In this article, we analyzed the morphological evolution of the sunspot and solar calcium plage groups recorded at the Ebro Observatory in the period 1910–1937 to make predictions about several properties ... -
Temporal variation and asymmetry of sunspot and solar plage types from 1930 to 1936
(Advances in Space Research, 63, 11, 2019-02-23)Using the recently converted to digital format heliophysics catalogues of the Ebro Observatory published in the 1930s, we analyse simultaneously the temporal variation and asymmetry of two different ... -
The Evolution over Time and North–South Asymmetry of Sunspots and Solar Plages for the Period 1910 to 1937 Using Data from Ebro Catalogues
(Solar Phys (2020) 295:99, 2020-07-23)In this work, we analysed both the evolution over time and the north–south (N-S) asymmetry of certain solar features with regards to their morphological type and area. We examined and compared simultaneously ...
