| Zusammenfassung |
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. In the period up to ad
1700, only five examples have been found of two or more oriental auroral
observations from separate sites on the same night. These occurred during the
nights of ad 1101 January 31, ad 1138 October 6, ad 1363 July 30, ad 1582 March
8 and ad 1653 March 2. The independent historical evidence describing
observations of mid-latitude auroral displays at more than one site in East Asia
on the same night provides virtually incontrovertible proof that auroral
displays actually occurred on these five special occasions. This conclusion is
corroborated by the good level of agreement between the detailed auroral
descriptions recorded in the different oriental histories, which furnish
essentially compatible information on both the colour (or colours) of each
auroral display and its approximate position in the sky. In addition, the
occurrence of auroral displays in Europe within two days of auroral displays in
East Asia, on two (possibly three) out of these five special occasions, suggests
that a substantial number of the mid-latitude auroral displays recorded in the
oriental histories are associated with intense geomagnetic storms.
