Short description of project
Investigation of the Solar differential rotation using coronal bright points as tracers. Investigation of the visibility of coronal holes in microwaves. 
Short description of the task performed by Croatian partner
Extension of the measurements of the differential rotation to the SOHO-EIT data set from October 1999 to March 2000. It was shown that the most important contribution to the brightness temperature in coronal holes comes from regions of enhanced density in the transition region and lower corona and that thermal bremsstrahlung can explain the  existence of regions with lower as well as higher brightness temperature inside coronal holes.
