15 Years of Spectacular Observations - II

Another spectacular image was created in celebration of 15 years of Hinode observations. This image was prepared with the Hinode Science Center at National Astronomical Observatory of Japan using XRT full-Sun images archived at XRT Synoptic Composite Image Archive.

Since the beginning of the mission in late 2006, Hinode has been observing the Sun across the whole activity cycle. During these observations, Hinode has recorded the drastic change of Sun's magnetic activity, as represented by the variation of Sun Spot Numbers.
