We present the Optical Flow algorithm for forecasting the Rate Of total electron content Index (OFROTI). It consists of a method for predicting maps of rapid fluctuations of ionospheric electron content in terms of Global Navigation Satellite Systems (GNSS) dual-frequency phase measurements of the rate of change of total electron content index (ROTI). The forecast is made in space and time, at horizons up to more than 6 hours. These forecast maps will consist of the ROTI spatial distribution in the northern hemisphere above 45 degrees latitude. The prediction method models the ROTI spatial distribution as a pseudo-conservative flux, i.e., exploiting the inertia of the flux of ROTI to determine the future position. This idea is implemented as a modification of the Optical Flow image processing technique. The algorithm has been modified to deal with the non-conservation of the ROTI quantity in time. We show that the method, can predict both; the local value of ROTI and also the regions with ROTI above a given level, better than the prediction using the current map as forecast. I.e., predicting by a current map from horizons of 15 minutes up to 6 hours. The method was tested on 11 representative active and calm days during 2015 and 2018 from the multi-GNSS (GPS, GLONASS, Galileo, and Beidou) multifrequency measurements of more than 250 multi-GNSS receivers above N45 degrees latitude, including the high rate (1Hz) measurements of Greenland GNET network among the International GNSS Service network.
