Abstract: We investigate the properties of coronal holes using a histogram-based intensity thresholding technique. The area and the coordinates of the centroid were determined for a coronal hole observed by SOHO/EIT and Hinode/ XRT on 20-26 May 2007. This hole was also associated with a significant increase in the mean solar wind speed measured by ACE at L1.
