Refer to the above picture.
An unipolar group (one big umbra) with penumbra.
This sunspot seems to fit into class H of McIntosh Sunspot Classification Scheme.
I referred to the website http://gloria-project.eu/wp-content/uploads/2013/10/learning-sunspots-classification-10.1.1.107.6641.pdf for the classification of sunspot.
