No. 1 Time (UT) 11:50 X-ray BP behaviour Magnetic fragment behaviour A small bipolar region locates at northwest of a positive dominant region. Both positive and negative fragments move toward each other in the bipolar region. Two polarities in the bipolar region touch each other, cancellation occurs. A BP emerges. A few positive fragments disappeared in the bipolar region. Both polarities keep touching. Cancellation continues in this region. A few strong negative fragments from southeast move toward the dominant positive fragments. Both polarities in the bipolar region become less and weaker. Cancellation continues. Negative fragments from the southeast keep moving toward the dominant positive one. The negative fragments in the bipolar region become very weak and have a certain distance from the positive one. The negative fragments from the southeast begin to touch some positive fragments outbound of the dominant ones. The negative fragment in the bipolar region emerges and becomes stronger again and then cancellation restarts. This cancellation gets X-ray response that flames the BP again. The negative fragment disappeared after 13:25, and the BP disappeared after that. Note

becomes and a peak in curve.

12:49

The BP disappeared. Another bright region with diffused structure emerges at its southeast.

13:05

The southeast bright region becomes brighter. The bright region becomes hardly visible. Another weak bright region emerged at its southeast and becomes stronger.

The negative fragments from southeast keep moving toward and begin to touch the dominant positive ones. Cancellation continues in this area. Those negative fragments touched the dominant positive ones disappeared. The remained negative ones pause moving toward the dominant positive, and part of them move toward and begin to touch another positive fragments at the southwest. At southeast, many weak positive fragments emerged and cancellation is observed in the area. Didn't find any X-ray response in the southwest cancellation site this moment. Brightening relates to this cancellation emerges around 14:03 when cancellation is continuing. And creates a peak in the light curve around 14:08. There is a gap between 14:31 and 14:42 in XRT observations.

A bright band A lot of small bipolar regions emerged and extending from distribute at the this directions. Cancellation is southeast emerges. frequent in this area.

The band becomes There is data gap in SOT from 14:40 to15:33, but Cancellation and flux emergence brighter and it can be observed those small bipolar become in this area flame the brightening creates a peak in stronger and more active before 14:40. sometimes again after 15:33. By the light curve of the end of the data set, activity in the area. this area become quieter and there is another "magnetic active region" observed at northeast and takes control the behaviour of the
