  Recent studies of radioisotopes in tree rings or ice cores suggest that
extreme space weather events occurred in the pre-telescope age. Observational
records of naked-eye sunspots and low-latitude auroras in historical documents
in pre-telescopic age can provide useful information on past solar activity. In
this paper, we present the results of a comprehensive survey of records of
sunspots and auroras in Chinese official histories from the 6th century to the
10th century, in the period of Su\'i, T\'ang, the Five Dynasties and Ten
Kingdoms. These official histories contain records of continuous observations
with well-formatted reports conducted under the policy of the government. A
brief comparison of the frequency of observations of sunspots and auroras with
the observations of radioisotopes as an indicator of solar activity during the
corresponding periods is provided. Based on our data, we survey and compile the
records of sunspots and auroras in historical documents from variouslocations
and in several languages, and ultimately provide these as open data to the
scientific community.
