While graphical records of astronomical/meteorological events before telescopic observations are of particular interest, they have frequently undergone multiple instances of copying and may have been modified from the original. Here, we analyse a gra

A further study is made of the validity of a technique developed by the authors to identify historical occurrences of intense geomagnetic storms, which is based on finding approximately coincident observations of sunspots and aurorae recorded in E

All the accessible auroral observations recorded in Chinese and Japanese histories during the interval AD 1840–1911 are investigated in detail. Most of these auroral records have never been translated into a Western language before. The East Asi

Comprehensive catalogues of ancient sunspot and auroral observations from East Asia are used to identify possible intense historical geomagnetic storms in the interval 210 BC-AD 1918. There are about 270 entries in the sunspot catalogue and about

The earliest known drawing of sunspots appears in The Chronicle of John of Worcester, which was compiled in the first half of the twelfth century. In this medieval chronicle, the Latin text describing the sunspots is accompanied by a colourful dra

Early auroral observations recorded in various oriental histories are examined in order to search for examples of strictly simultaneous and indisputably independent observations of the aurora borealis from spatially separated sites in East Asia. I

Using detailed knowledge of the Earth’s variable rotation, we conclude that the eclipse of BC 188 July 17 was total at Rome, and that Livy’s historical account of the darkness that befell the city in that year was due to this eclipse. This sets t

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 accompanied by detailed meteorological records t
