The active region displayed in Figure 1 show a larger pore and several smaller pores in G-band. Bright points and several micropores are also visible. This active region was observed from 18:08 UT to 23:38 UT. However, there are three gapes from
18:42 to 19:08 20:21 to 20:47 and 21:59 to 22:26. Figure 1 shows the first image of the time series.
Figure 2 illustrates the evolution of the fine structures at the inner part of the granules (i.e. towards umbra) at the pore boundary. Several dark striations can be seen at granules edges. Such striations being reported by \citet{pontieu06,scharmer02} and \citet{spruit10}. These striations are visible during the entire span of the time series.

The migrating filaments disappear into the umbra, leaving a bright dot. The evolution of such filamentary structures can be seen in the movie-I (attached as online material). The filament shown in cyan circle initially show a dark striation which develops into a 'Y' shaped and with time it migrates into the umbra, leaving a bright dot. Similarly, the filament indicated by a green circle evolve and disappear. The filament shown by the yellow circle also shows similar evolution, but an another filament evolve from it.
Figure 3 illustrates the evolution of such filaments from another part of the time series. Cyan and yellow circles indicate the evolution of broad filaments. Evolution of thin filament is indicated by a green circle.
Close inspection of the movie shows that this pore sustains its identity and these structures are not confined to a particular location on pore boundary, rather visible on other locations also. Only changes in a larger UD with multiple dark lanes and in the light bridge within the pore observed. Umbral dots at the periphery and within umbra can also be
