No filters used. Clouds acted as filter. Added labels and a magnified part of the Sun showing detail of the sunspot,

Today Nov 12th 2020 we had a cloudy day in Monterrey. The Sun was almost covered by clouds but they started braking a little bit enough to show to profile of the Sun circle. The clouds acted as filter but they allowed to capture a little bit of detail of the sunspot. It happened just a few seconds. After that, the Sun again was covered totally by clouds.
