The possibility that there is a lunar modulation of geomagnetic activity around the time of total lunar eclipses is considered. The modulation of activity, as seen in the Ap indices for the years 1932-1980, consists of a 4-day increase commencing 3 days before the eclipse day. This characteristic of the modulation indicates that it may be caused by entry of the moon into the magnetospheric tail and by the subsequent motion of the moon within the tail; it is not observed in conjunction with partial lunar eclipses. By using the aa indices, which are available back to the year 1868, it is possible to investigate the long-term temporal characteristics of the modulation. It is found that the increase in activity after 1932 is not replicated in the data before 1932 (during the years 1870-1931). It is concluded that the increase is most probably a statistical anomaly and that it would be inappropriate to conclude from it that the moon's entry into the geomagnetic tail enhances geomagnetic activity.
