Original Note:
As confused comments, due to no Context, UV image. Coronal H is simply lower temperature area on Sun, that looks black when the brighter areas are exposed correctly. But still bright. 12hr irrelevant, as gives no start point . They can last days. Nothing to worry or panic. https://www.swpc.noaa.gov/phenomena/coronal-holes
