Abstract

In this paper we present preliminary results on the solar differential
rotation measured tracing coronal bright points in SDO/AIA images. An
automatic recognition method was applied to the series of images taken in
the test period, 1-2 January 2011.
Coronal bright points are suitable tracers for the determination of the solar
differential rotation, because they are localized objects which are very
well distributed over solar disc. Results presented in this paper
show that the SDO/AIA data are very useful for that aim, due to the high spatial and
temporal resolution of the images.
