A completion of the catalog of polar aurorae observed in lower latitudes in 1001-1779
 Střeštík, Jaroslav
In 1985 Křivský and Pejml published a catalog of polar aurorae observed in 1001-1900 in latitude lower than 55°N. In 1996 Křivský published a supplement to this catalog. This common catalog collects all data concerning the aurorae published earlier and it was in its time the most complete one. In 2004 appeared till now unknown data about polar aurorae observed in Korea in 1001-1779, These dta are, only with a few exceptions, not included in the catalog of Křivský, and vice versa. here the comprehensive catalog is presented, containing the Křivský's data s well as those from Korea. Further some regularities in the occcurrence of aurorae are presented using the comprehensive catalog. The distribution of aurorae in time agrees well with the reconstructed series of sunspot numbers and displays similar periodicities, especially the long-term ones.
