Original abstract
The presented paper deals with a new method for measurement of the differential rotation rate of the solar photosphere. This method is based on shift measurement using the phase correlation, which does not require any tracing points and long observation over many days and weeks. The method was applied on images taken at 1700- A by the Atmospheric Imaging Assembly (AIA), a part of the Solar Dynamics Observatory (SDO) mission. The results of our measurements are latitudinal dependences of the sidereal rotation period determined from couples of images.

Článek se zabývá novou metodou měření rychlosti rotace sluneční fotosféry. Podstatou této metody je měření posuvu pomocí fázové korelace, která nevyžaduje žádné tracing body a dlouhá pozorování. Metoda byla aplikována na snímky pořízené při vlnové délce 1700 angströmů ze zařízení Atmospheric Imaging Assembly (AIA), které je součástí mise Solar Dynamics Observatory (SDO). Výsledkem našeho měření jsou závislosti periody siderální rotace na heliografické šířce, které byly určeny s dvojic snímků.
