I was trying out the ND 100,000 filter in preparation for Eclipse Day. At after 3 pm, the photo showed a giant sunspot which got me excited. I took another photo an hour later and saw that the spot moved. Since the sunspot was so huge, I thought it will be mentioned somewhere on the internet. Wham! On EarthSky. I had captured AR 3590. This sure made me superexcited.
