July 5, 1980, Lake Nävsjön, near Nävekvarn. Peder Eriksson, Sören Unnskog and Ann-Kristin Unnskog were angling at 2350 hours when they saw a large ball-shaped object which descended towards the water-level of Lake Nävsjön. The object came near to the witnesses and changed colour as it changed speed. Most often it was yellow-white at the centre and reddish round the edge. No noise heard.
