This 4-panel mosaic of the Sun shows the activity that was taking place
on January 6, 2012. As the image shows, there were many prominences,
several filaments, and many sunspots or active regions. Sunspot 1391 is
visible in the active region to the left of center, while the active
region to the right of center shows sunspots 1389 (left) & 1388
(right). Just above center, but below the filament in this image, is a
small sunspot, 1393, and diagonally up to the right of 1393 is sunspot
1392. The sun's everchanging features makes it a joy to image over and
over again.
