Historical Supernova Explosions in Our Galaxy and Their Remnantsthese records are from East Asia (i.e. China, Japan and Korea), although the most recent historical supernovae have European records, and there are a variety of Arabic records also available for some events. Here I review these records of the historical supernovae, and the modern observations of the supernova remnants that they have produced.

’Abd al-Raḥmān al-Ṣūfī’s 3-Step Magnitude Systemhat al-ḥūfī used what we have termed a ‘3-step intermediate magnitude system,’ which is more accurate than Ptolemy’s 2-step intermediate system. In this paper we examine in detail the accuracy of this unique 3-step system in comparison with Ptolemy’s and modern magnitude values.

Determination of Δ, and Lunar Tidal Acceleration from Ancient Eclipses and Occultationsen 198 and 181 BC in China and in Rome give a value for the lunar tidal acceleration that is consistent with the current one. We also show that the records of lunar occultations of Venus and Saturn in AD 503 and 513 in China are useful for our studies of the Earth’s rotation.

The Legendary Fourth-Century Total Solar Eclipse in Georgia: Fact or Fantasy?ue of Δ. inferred from written sources agrees well with generally-accepted values, such as those derived by Morrison and Stephenson (., 327–336, 2004), namely, Δ. ≈ 7,450 ± 180 s. We also show the extent to which this TSE would have seemed remarkable to observers at Mirian’s presumed location and less so to those nearby at lower elevations.
