Image Details
Caption: Figure 1.
Fe XV intensity image of AR 10961 tracked from close to the center of the Sun (2007 August 1) to the limb (2007 August 8). All the images have been plotted with the same field of view of 297'' ×197'' in order to help us track any AR structure through the solar rotation. Though all the AR data have been plotted with the same y-axis scale, the scalings in the x-axis are different. This is because the apparant heliographic longitude (the solar X coordinate) of the AR changes vastly over the solar rotation, unlike the latitude (the solar Y coordinate).
