AR3790 and AR3796 (the spot groups to the left of and above and below the single spot on the right side in this image), have the potential to produce M-Class flares. Note also the small group of tiny spots below and in line with the single spot. This is AR3800. It is a relatively high-latitude spot and it tells us something about the current solar cycle (number 25). High latutude spots tend to appear at the early stages of a solar cycle; spots migrate towards the equator as the cycle matures and moves toward maximum. The presence of these spots indicates we are still in the early stages of cycle 25, and could have another 2-3 years of strong solar activity.
