Records of sunspot and aurora observations in pre-telescopic historical documents can provide useful information about solar activity in the past. This is also true for extreme space weather events, as they may have been recorded as large sunspots observed by the naked eye or as low-latitude auroras. In this paper, we present the results of a comprehensive survey of records of sunspots and auroras in the Sòngshǐ, a Chinese formal chronicle spanning the tenth to the thirteenth century. This… 
Records of sunspot and aurora activity during 581–959 CE in Chinese official histories concerning the periods of Suí, Táng, and the Five Dynasties and Ten Kingdoms
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
Historical space weather monitoring of prolonged aurora activities in Japan and in China
Great magnetic storms are recorded as aurora sightings in historical documents. The earliest known example of “prolonged” aurora sightings, with aurora persistent for two or more nights within a 7
A Transit of Venus Possibly Misinterpreted as an Unaided-Eye Sunspot Observation in China on 9 December 1874
Large sunspots can be observed with the unaided eye under suitable atmospheric seeing conditions. Such observations are of particular value because the frequency of their appearance provides an
Unaided-eye Sunspot Observations in 1769 November: A Comparison of Graphical Records in the East and the West
Sunspots can be seen with the unaided eye when they are sufficiently large. Due to the known correlation between the occurrence of unaided-eye sunspot observations and the phase of the solar cycle,
Non-parametric Data Analysis of Low-latitude Auroras and Naked-eye Sunspots in the Medieval Epoch
We have studied solar activity by analyzing naked-eye sunspot observations and aurorae borealis observed at latitudes below 45∘$45^{\circ}$. We focused on the medieval epoch by considering the
A great space weather event in February 1730
Aims. Historical records provide evidence of extreme magnetic storms with equatorward auroral extensions before the epoch of systematic magnetic observations. One significant magnetic storm occurred
Sunspot Observations on 10 and 11 February 1917: A Case Study in Collating Known and Previously Undocumented Records
An extensive investigation of ships' logs, as part of the Old Weather citizen‐science project, identified a sunspot observation made from HMS Hilary on 10 February 1917. This sunspot record was
East Asian Observations of Low Latitude Aurora during the Carrington Magnetic Storm
The magnetic storm around 1859 September 2, caused by so-called Carrington flare, was the most intense in the history of modern scientific observations, and hence is considered to be the benchmark
