Faint Light Bridge on Sunspot AR2939

 


Sunspot AR2939 was observed on Feb 5, 2022 using a solarfilter ND3.8 and OIII filter with Nikon D7500 and TAL200K f/8.5. The picture is cropped and show the sunspot together with pores and the faint light bridge inside the umbra. This is the first time I made this observation.
