  This report uses a few well documented cases of Ball Lightning (or BL for
short) observations to demonstrate a correlation between BL and positive
lightning, especially strong positive lightning. This allows to draw
conclusions and predictions about future BL observations and the pro- duction
of these objects in the laboratory. Contrary to many current BL theories, these
objects can be created without direct contact to a lightning channel. Very high
electric fields appear to be essential for the creation, together with the
proper temporal structure of the field. So far no experiments have been
performed along the ideas presented in this report.
