Cancellation occurs. The BP becomes stronger. Positive fragments, which just disappeared, emerge again and become stronger at the side of the negative ones. Cancellation continues between them. A few other positive fragments move toward the negative ones. The main positive and negative fragments become closer. Both polarities become more concentrated. Some negative fragments move toward the positive ones and cancellation occurs. Cancellation continues. Many positive and negative fragments disappeared. Scattering negative fragments keep moving toward the positive ones. The concentrated negative fragment doesn't move very much.

The BP reaches its highest peak of its light curve.

The BP ejects a few jet-like features at different directions. The BP itself becomes smaller.

Both positive and negative fragments outside the site keep moving into. The BP flashed a little, but it keeps similar brightness level as before. The BP reaches another strong peak of its light curve. The negative fragments touch the main positive ones. Cancellation continues. A few positive and negative fragments disappeared. The main positive fragments become smaller. Another strong negative fragment move toward the positive ones. The BP is controlled by the activity of this region. At 05:13, it reaches another peak, when a few negative fragments are touching the main positive ones.

The positive fragments start to touch the main negative ones. At the other side of the negative ones, some other positive fragments move closer and closer. A bipolar region emerges far away from the positive ones. It becomes stronger and moves toward the positive ones. The emerged bipolar touches the positive ones. Positive fragments moving from the other side touch the main negative ones. The main positive Cancellation in this site is roughly coincident with the brightness of

the BP. When the BP gets stronger, there normally is strong cancellation, but sometimes strong cancellation doesn't get X-ray response. The BP becomes very bright but small at the end of the data set. The main positive fragments is still touching the negative ones. Many of them disappeared and the remained become much smaller.
