Bošković's Spherical Trigonometric Solution for Determining the Axis and Rate of Solar Rotation by Observing Sunspots in 1777
Mirko Husak, Roman Brajša, Dragan Špoljarić +5
In September 1777 Ruđer Bošković observed and measured the sun-spot positions to determine the solar rotation elements. In 1785, among other methods, he described a trigonometric s…

Bošković's method for determining the axis and rate of solar rotation by observing sunspots in 1777
Mirko Husak, Roman Brajša, Dragan Špoljarić +5
In 1777 Ruđer Bošković observed sunspots, determined their positions and the solar rotation elements by his own methods briefly described here. We repeat his calculations of the me…

Validity of the relations between the synodic and sidereal rotation velocities of the Sun
I. Skokić, R. Brajša, D. Roša +2
Existing methods for conversion between synodic and sidereal rotation velocities of the Sun are tested for validity using state of the art ephemeris data. It is found that some of…
