Abstract: Evidence is presented from normal run magnetogram data of Huancayo, Kodaikanal and Kakioka to show that geomagnetic solar flare effect (SFE or Crochet, occurs not only in the sunlit hemisphere but also in dark hemisphe reo Using a selected sample of five events observed over the period 1969-71, it is noticed that discrepancy exists between the observed characteristics of nighttime geomagnetic SFE and those expected from the interpretation that the nighttime geomagnetic SFE is due to induced currents that are forced to flow into the ,dark. hemisphere owing to the sudden increase in electrical conductivity of the sunlit hemisphere. This discrepancy may be due to some of the inherent assumptions of the theoretical model used .for calculating the characteristics of induced currents in the dark hemisphere.
