All the data obtained with Hinode have become open to public on 27th May, 2007. Tremendous data have been obtained with three telescopes on Hinode since their first lights in October 2006. We prepared a long-term movie of full Sun images taken with XRT to demonstrate the evolution of dynamic corona.

X-ray bright points in quiet region (2007 March 16, 00:00 - 08:00 UT)

Many X-ray bright points have been found in close-up movie of quiet region. Thanks to high resolution of XRT, it has become evident that X-ray bright points are actually loop structures. The movie indicates ubiquitous activities of X-ray bright points, even in the quiet region. The X-ray bright points are marked with green circles in the following panel. Definition of "quiet region" might be changed by Hinode observations.
