Interesting Sunspot displays both days.
I now attach three images.
One shows Sunspots revealed in White Light using my 88mm refractor & Opticstar PL-131m video on 20th July.
Another W.L. image Sunspots on 21st July, a Hydrogen Alpha image 21st July shows supergranulations and brighter patches related to Sunspot activity.
Best wishes from Cliff
