Scientific paper

A scintillation activity index which provides an objective method for the identification of interplanetary features such as discrete ejecta and corotating streams was developed. Its effectiveness in predicting several sudden impulse events and correlating with geomagnetic activity is demonstrated. Using the Interplanetary Scintillation (IPS) activity index, I35, a data set during Feb. to Apr. 1992 was examined. A good correlation between the activity seen in interplanetary space and geomagnetic activity was found. Apparently, the onset of the most significant event in the geomagnetic index, Ap, is observed several days earlier using the IPS technique. Also, using a prediction technique developed for the IPS index, an 'event approaching' was predicted on six days, all of which occur on either the day of a sudden impulse or within the three days prior to a sudden impulse. One IPS event apparently unrelated to Ap or sudden impulse activity was found. This is proposed to be due to an event missing the Earth or to an event with a northward directed magnetic field which is unlikely to cause a significant impulse to the Earth's magnetic field.
