Aims: We present examples of the time evolution of phenomena occurring in the quiet Sun photosphere as seen from observations of high spatial and spectral resolution and with a time cadence of 23 s. Methods: A time sequence of about 5 min has been taken with the Göttingen Fabry-Perot spectropolarimeter at the VTT in the Fe I 6173 Å line. The data were reconstructed with speckle methods. Results: With a polarimetric sensitivity of 2 × 10-3~Ic (σ_B=2 G), the formation of a bright point as seen from broadband and line-minimum intensities, as well as in magnetograms and Dopplergrams can be traced in detail. Other events, like a stable mixed-polarity configuration in the intergranules and the appearance of magnetic signature above granules in both dark and bright areas are presented.
