Real Time Prediction and Observation of Interplanetary Events

We describe interplanetary-scintillation observations associated with solar events on 7 and 8 May 1992. The unique feature of these observations was that, for the first time, scintillation enhancements were predicted in real time by observing solar events on these dates and then detected at Ooty and Cambridge observatories. Good consistency between the all-sky images (g-maps) from both observatories were found. Ooty's high resolution (~100 sources sr^(-1)) solar wind velocity maps, obtained for the first time, support a simple physical model based on two dimensional MHD, time dependent, propagating shock structures.
