TL;DR: SDS-2015 was discovered by the Hubble Space Telescope (HST) in 2015 as mentioned in this paper, and the size of the dark spot did not exceed 20 degrees of longitude, more than a factor of two smaller than the Voyager dark spots, but only slightly smaller than previous northernhemisphere dark spots.
