We present measurements of two types of cluster galaxy alignments based on avolume limited and highly pure ($\ge$ 90%) sample of clusters from the GMBCGcatalog derived from SDSS DR7. We detect a clear BCG alignment (the alignmentof major axis of the BCG toward the distribution of cluster satellitegalaxies). We find that the BCG alignment signal becomes stronger as theredshift and BCG absolute magnitude decrease, and becomes weaker as BCG stellarmass decreases. No dependence of the BCG alignment on cluster richness isfound. We can detect a statistically significant ($\ge$ 3 sigma) satellitealignment (the alignment of the major axes of the cluster satellite galaxiestoward the BCG) only when we use the isophotal fit position angles (PAs,hereafter), and the satellite alignment depends on the apparent magnitudesrather than the absolute magnitudes of the BCGs. This suggests the detectedsatellite alignment based on isophotoal PAs from the SDSS pipeline is possiblydue to the contamination from the diffuse light of nearby BCGs. We caution thatthis should not be simply interpreted as non-existence of the satellitealignment, but rather that we cannot detect them with our current photometricSDSS data. We perform our measurements on both SDSS $r$ band and $i$ band data,but did not observe a passband dependence of the alignments.
