A simple model is set up to consider the effects of horizontal conduction of heat away from a region of electron precipitation in the upper atmosphere. It is shown that a given precipitated flux produces a much smaller increase of temperature in a region of the order of 1 km in width than it does in one several hundred km wide. A method is developed and illustrated, by which it is possible to determine whether healing of the neutral atmosphere is negligible during such precipitation events, thus allowing the use of static atmospheric models in the theoretical treatment of the effects.
