On the basis of ground observations at Godhavn (77°INV) during the period from September 1988 to March 1989,we studied the characteristics of auroras on the higher latitude side of the aurora oval. Four typical kinds of auroras are seen in this region during this period. They are (a) bright poleward expansion auroras, (b) transpolar auroras, (c) sun-aligned arcs, and (d) morning side bright auroras. The intensity of (a), (b) and (d) auroras are very strong and these auroras are similar to those observed along the auroral oval. The sun-aligned arcs (c) are the typical aurora seen only on the high latitude side of the auroral oval. The relationships between these auroral features and other related phenomena are also discussed.
