Short description of project |
Measurements of the Solar differential rotation using various tracers.
Whole disc SOHO-EIT images (Fe XV, 28.4 nm) are used to trace coronal bright points.
A comparison of the achieved accuracies of position measurements using recent Kanzelhoehe PHOKA images and Kanzelhoehe sunspot drawings is performed. |
Short description of the task performed by Croatian partner |
Development of the interactive and automatic method of measurement and its application on the SOHO-EIT data set from June 1998 to May 1999.
Development of the software program Sungrabber for the determination of the positions of sanspots on the drawings secured at Kanzelhoehe Observatory. |
