We followed active region NOAA 0030 from July 14 to 21, 2002 at Big Bear Solar Observatory(BBSO). High resolution images at 5200 continuum and NIR 1.56 \mu were taken continuously for about 3 hours each day. We applied speckle reconstruction technique on 5200 continuum data to get diffraction limit images. Combined our images with MDI magnetograms, we are able to study the structure, evolution and flows of faculae and small pores. In addition, we obtained data of several other active regions, NOAA 0031, 0035, 0036. These images were used to study the Center-to-Limb variation of facular contrasts. Finally, we compare the results of this study with that for the data sets we obtained in August and September 1999.
