On the Determination of the Solar Rotation Elements i, Ω and Period using Sunspot Observations by Ruđer Bošković in 1777
In September 1777, Ruđer Bošković observed sunspots for six days. Based on these measurements, he used his own meth-ods to calculate the elements of the Sun’s rotation, the longitude of the node, the inclination of the solar equator and the period. He published a description of the methods, the method of observation and detailed instructions for calculations in the second chapter of the fifth part of the Opera in 1785. In this paper, Bošković’s original calculations and repeated calculations by his procedure are published. By analysing the input quantities, procedures, and results, the input quanti-ties of the error, and the calculation results are discussed. The reproduction of Bošković’s calculations is successfully re-produced and we obtained very similar results. The conclusion proposes a relationship of Bošković’s research with mod- ern astronomy.
