Sun - 10.9.2021 at 12.30 - 10.9.2021 at 12.35 Tampere Observation number 101177

Visibility III / V

Kari A. Kuure, Tampereen Ursa

As the cloudiness receded a bit, I managed to find a relatively clear opening in the upper clouds from which I photographed the Sun and its abundant spots. However, the aperture was not entirely clear as a thin upper cloud did appear, however, and it emerged in the post-processing of the image, as everyone will surely notice it in this image.

Today’s sunspot count, 124, is relatively high at this time of the sunspot period. Indeed, it appears that the activated has evolved remarkably rapidly in a higher direction when compared to predictions.

On September 11, 2021, I added a 2 × magnified and cropped image of the most spectacular comma groups. I reprocessed the original images and increased the size during the stacking step. I did the crop in post-processing.
