Present status of the recovery phase of cosmic ray 11-year modulation

The recovery from cosmic ray 11-year modulation follows two distinct repetitive patterns [Ahluwalia, 1994]. When the magnetic polarity of the Sun in the northern hemisphere is negative (qA < 0), the recovery is completed in 5 to 8 years but for the positive magnetic polarity epochs (qA > 0) the recovery period is reduced to less than half as much. These repetitive patterns have been observed for the last five solar activity cycles (17 to 21). The recovery for cycle 22 is Still in progress. By the end of 1994, the intensity monitored with the nuetron detectors at Deep River, Climax, and Huancayo continues to be significantly below the cosmic ray maxium observed in March 1987. The physical significance of our results is discussed.
