Abstract: The characteristics of the ionospheric storm of 4-6 Dec. 1958 in the Indian sector (60-85°E) are studied using published data from ten ionospheric stations distributed from high midlatitudes to dip equator. It is shown that in the electrojet region, besides the well known positive effects in f0F2due to a weakening of the electrojet, negative effects in f0F2 with prominent increases in height of F2-layer also occurred during this particular storm. It is suggested that changes in atmospheric neutral composition (i.e. increased N2/O and O2/O ratios) are the basic causes of the negative effects in foF2 in the electrojet region noticed for this storm.
