| Popis: | The focus of this article is a re-count of Richard Carrington's original sunspot observations from his book drawings (Carrington,1863) by an observer from the World data Center-SILSO network, Thomas H. Teague(UK). This modern recount will enable the use of Carrington's observations in the re-computation of the entire Sunspot Number series in a way Carrington's original counts (Casas and Vaquero,2014) did not. here we present comparison studies of the new recounted series with contemporary observations, new data extracted from the Journals of the Zurich Observatory and other sources of Carrington's own observations and conclude that Carrington's group counting is very close to the modern way of counting while his method for counting individual spots lags significantly behind modern counts. We also test the quality and robustness of the new re-count with methods developed in Mathieu et al.,2019. Comment: 30 pages, 19 figures few of them have subfigures, this article will be submitted to Solar Physics in future |
