Solar rotation elements $i, \Omega$ and period determined using sunspot observations by Ru{\dj}er Bo\v{s}kovi\'c in 1777

Autor: Husak, M., Brajša, R., ŠPoljarić, D.

Publikováno v: Central European Astrophysical Bulletin, 45, (2021) 1, 1-7

Ru{\dj}er Bo\v{s}kovi\'c developed methods for determination of solar rotation elements: the solar equator inclination i, the longitude of the node {\Omega} and the period of solar rotation. In his last work Opera pertinentia ad opticam et astronomia

Report

Determination of the Solar Rotation Elements and Period from Ru{\dj}er Bo\v{s}kovi\'c's Sunspot Observations in 1777

Autor: Roša, D., Hržina, D., Husak, M., Brajša, R., Špoljarić, D., Skokić, I., Maričić, D., Šterc, F., Romštajn, I.

This paper focuses on the observations of sunspots made by Ru{\dj}er Bo\v{s}kovi\'c in 1777. We derived the expressions needed to calculate the elements of the Sun's rotation and period from observations. We used modern ephemeris data in the processi

The disturbance-driven changes of periphytic algal communities in a Danubian floodplain lake

Autor: Žuna Pfeiffer T., Mihaljević M., Špoljarić D., Stević F., Plenković-Moraj A.

Publikováno v: Knowledge and Management of Aquatic Ecosystems, Vol 0, Iss 416, p 02 (2015)

Disturbance event-driven changes in periphytic algal communities were studied in a Danubian floodplain using artificial substrata (glass slides). The hydrological regime of the river-floodplain system strongly influenced the physical and chemical env
