the Importance of this event The significant intaresting body as very large and very low albedo, but this asteroid has not been studied much. We'll obtaine good shape of this asteroid by many observers coopetaion. E We hope to make the relationships of asteroidal observation among East Asia. E The improvement of observation against the small drop mag event. E The making studies for next age young observers like as collage students. Note for observation The observers should use large telescope and take long integtration shutter rather than usual asteroidal event to take stable star image, because this event will have very small dmag and low altitude.
