The solar active region of #2192, observed from Oct 18 to 29, 2014, has evolved with a span of about 20 degrees in solar longitude and sunspots of over 50, the largest one in last ten years.
We could observe the group only naked eye through the solar filter.
This page shows you the change of group for 4 days, the image has been displayed by turning the celestial north direction upward. The sunspot group is moving toward the solar rim, its apparent aspect changes daily. The group has a pair of bipolar principal sunspots and surrounding penumbra with complicated shapes, and tiny spots distributed around them. It can be detected that the detailed structures are changing every day. |  Full-disk image with white-light (Oct 25) |

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. |
