  Naked-eye sunspot observations (NESO, hereafter) have been recorded for last
two millennia, approximately. This kind of records were made around the world,
mainly in Asian civilizations, and they are compiled in several catalogues. In
this work, we analyze solar activity in days of the 19th century when NESO were
recorded. We found that only more than five sunspot groups were recorded in 39
% of days corresponding to these NESO events. Furthermore, regarding the
largest groups observed in days when NESO were reported, we show the
uncorrected areas of these groups were below 200 millionths of solar disc (msd
hereafter) in 3.2 % of total cases while it is 12.9 % for areas between 200 and
499 msd. Thus, NESO records do not imply high solar activity and big sunspot
groups necessarily. Therefore, these results contradict the interpretations of
recent works that, using the same NESO set, suggest the solar activity level
during the Maunder Minimum is still an open question. NESO records support the
Maunder Minimum as a very low solar activity period.
