Abstract : Till now, The activity of low and middle latitude has been studied

           from all points. In this study, we study about the natures of the
           `activity' of high latitude corona with the Yohkoh SXT data from
           the start of the Yohkoh observation to the middle 1995 as follows.

1. The period for the variability of average DN values

2. The gap, between Northern and Southern hemisphere, of the period for the variability of average DN values

3. The period for the activity of Northern and Southern hemisphere

4. The correspondence of the north and south asymmetory of the average DN value peaks and the sunspot positions

5. Solar rotation velocity for corona and coronal hole
