North-south asymmetry in sudden disappearances of solar prominences.
Abstract
The authors present the results of a study of the N-S asymmetry in SD of solar prominences during solar cycles 18 - 21. The N-S SD asymmetry curve is not in phase with the solar cycle and peaks about the time of solar minimum, the asymmetry reverses in sign during the solar maximum. This change of sign is coincident with the reversal of the Sun's magnetic dipole. The SD asymmetry curve can be fitted by a sinusoidal function with a period of eleven years.
