                         (MSTIDs) was measured for 1 year from the eastern tip of Brazil, 
                         about 10 degrees degrees south of the magnetic and geographic 
                         equators using spaced fixed frequency radio transmitters. The 
                         motion was very similar during all of the year. The daytime 
                         average direction was towards 150 degrees azimuth (clockwise from 
                         north) and speed was typically in the range 150-300 m/s. The 
                         azimuth varied only slightly during the day being slightly more 
                         easterly during evening-morning hours. During winter months there 
                         were also some TIDs whose motion was northward. None of the known 
                         sources for MSTIDs fits well with MSTIDs having these velocity 
                         patterns. A possible unconfirmed source is the Inter-Tropical 
                         Convergence Zone (ITCZ). Citation: MacDougall, J., M. A. Abdu, I.
