Using the "dynamo theory" method to predict solar activity, a value for the smoothed sunspot number of 109 ± 20 is obtained for solar cycle 22. The predicted cycle is expected to peak near December, 1990 ± 1 year. Concommitantly, F 10.7 radio flux is expected to reach a smoothed value of 158 ± 18 flux units. Global mean exospheric temperature is expected to reach 1060 ± 50K and global total average total thermospheric density at 400km is expected to reach 4.3 × 10 −15 gm cm −3 ± 25%.
