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: You may go blind, or your eyesight may fail when you observe or take pictures of the sun without right knowledge about reduction of sunlight. I do not take responsibilities for any accidents and/or damages by observing the sun even if this web page was how it all started.
