Thought i was going to make small test app to see the pattern rotation, but i quickly realized about your texture that:
1) The moon spheres are overlapping. You can't clearly distinct the border between each animation frame.
2) You are using jpg for image that clearly needs alpha channeled transparency. Please use PNG for this, because from JPG it is impossible to extract random shades of purple. JPG is not color or pixel perfect format.
3) Your texture size is not in power of 2. 579 x 579 is awkward size to load... graphics engines would load it as 1024x1024. Maybe you could squeeze it in 512x512.
Also when you divide 579 pixels with 8 spheres, you get PatternWidth that is 72.375, which further tells about the overlapping.
