As early as 2016, the NASA solar dynamic Observatory published a picture of a solar activity composed of 23 photographs, time from January 11, 2015 to January 21, 2016, to record the sun's trajectory in the year. The purpose of this map is to facilitate scientists to observe sunspots, flares and coronal mass ejections in solar activity.

The Solar Dynamics Observatory (SDO), a space mission satellite launched by NASA in 2010, is part of the Living With a Star (LWS) plan to observe the relationship between Japan and the earth.
