The image with2a eld-of-view of 12,000 30,000 km show many bright features at small scales that areembedded in the granulation pattern close to an active region.2’Daumenkino’: The 67 images (3700 3700 km ) cover a time period of about 18 minutesillustrating the fast horizontal movements of the features called G-band bright points.ivIn the context of this thesis the following articles have been published:Journal papers Langhans, K., Schmidt, W., 2002,Center-to-limb-variation of the G-band lines at 430.5 nmAstronomy & Astrophysics, v. 382, p. 312 Tritschler, A., Schmidt , W., Langhans , K., Kentischer, T.
