A method is described for obtaining the parameters of the equatorial electrojet on individual days using a new model of the electrojet and data from a few observatories close to the same longitude. Preliminary results of applying this to the equatorial electrojet in India are given. The electrojet seems to be wider in Peru and narrower in Nigeria than in India. The intensity of the electrojet is negatively correlated with the intensity of the world-wide Sq current. The fluctuations in electrojet parameters in September 1958 are given.
