Abstract

Full-disc solar images obtained with the Extreme Ultraviolet Imaging Telescope on board the Solar and Heliospheric Observatory were used to analyse solar differential rotation determined by tracing coronal bright points. Rotation velocity residuals, meridional motions and their relationship are investigated for a new data set from October 1, 1999 to March 31, 2000. Further we take care for the evolution of the single structures, dividing them into Point-Like-Structures, Small Loops and Small Active Regions and analysing their variation in intensity and size.
