The properties of penumbral grains (PGs) in a medium size sunspot are studied from a 4,5 h observation series observed on 1993 June 5 at the Swedish Vacuum Solar TelescopeLa Palma. The application of an image segmentation procedure yields a set of 605 penumbral grains which are investigated by a feature tracking algorithm.
