This page shows you the change of solar surface for 9 days by using of normal white light (left column) and H-alpha light (right column). I have performed the pseudo-color process on H-alpha images.
Although the solar activity has been just in its minimum, a large-scaled sunspot group of #0960 has appeared. You can see the movement and change of the group. The group has a bright region (the Plage) in its circumference, this indicates that the solar chromosphere is acting intensively.

Warning: When using a telescope for observing or photographing the sun, lacking knowledge of proper solar filtering methods can pose risks of visual impairment or blindness.
I do not assume any responsibility for any accidents that may occur as a result of observing or photographing the sun through this site.

Sunspot Group #2192 in Oct 2014:
