The concern with predictions will be discussed within the context of useful measureable parameters, possible models and actual needs. The longitudinal confinement of penetrating electric fields either enhancing or inhibiting ESF perhaps represents the ultimate clue to a successful scheme for handling day-to-day variability. ---------------------------------------- Upper Atmosphere and Ionosphere
