Tiny suspots are often just a small part of a larger ‘active region’ seen only in non-visible wavelengths. Looking at the space weather bulletin for that period, region AR12836 does appear to move from longitude 57 to 62 degrees. The bulletin is prf2392, and can be found at ftp://ftp.swpc.noaa.gov/pub/warehouse/2021/Weekly/PDF/ and shows other activity as well. I wonder whether the dark spot that we see does appear to move as the magnetic structure that caused it changes under the surface? They certainly can often be seen to rotate from day to day.
