I took a total of 07 nos of pictures of the Sun with Sun-spots ; at 8 am , 10 am , 11 am, 12 pm, 1 pm , 2 pm & 4 pm. ( all time are GMT + 5hr 30 minutes)
I missed the 9 am & 3 pm pic due to the clouds. I blend all 7 pictures in the same frame

The Sun apparently crosses a total 360 degrees of the Celestial sphere in a day (in 24 hours). I chose 8 am to 4 pm ( 8 hours) for doing this experiment on 25th September from Kolkata, India (22.49 N, 88.38 E). That day sunrise time was 5.26 am and Sun set time was 5.30 am, that means day time & night time are very near to equal.
So the sun should cross 120 degrees in 8 hours in the celestial sphere. That means the Sun's polar axis will rotate apparently from left to right and that would be 120 degrees also. And that can be proven through the apparent clockwise rotation of sunspots on “solar disk” from morning to evening.

I missed the 9 am & 3 pm pic due to the clouds. I blend all 7 pictures in the same frame and through this all sunspots are plotted in a single solar disk. I rotate this blended picture and put the 12 pm at the same position of 12 o'clock.
Now it just looks like a CLOCK where the sunspots are plotted as a time dial. Sunspot at 8 am is near about 9 ‘o clock position and Sunspot at 4 pm is near about 2 o'clock. That means it's approx. 120 degrees.
*One thing I noticed is that the sunspot's apparent angular movement is slightly less in the morning and evening than at noon time.
* In the picture, the Sun's North Pole is not at top.
