Van Allen and Decker (1988) have drawn attention to the anomalous behavior of several solar and interplanetary phenomena in 1980 and suggested the anomalies are caused by the reversal of the solar polar magnetic field polarity. However, I show anomalous behavior of geomagnetic activity in that year that could not have been due to any event associated with all solar maximums. I suggest the 1980 anomaly may be connected with the declining phase of the 88 year cycle of the sun and solar terrestrial relations.
