Abstract. We analyse the solar cycle (SC) 23 behavior. We also make a comparison with some
previous cycles and present a few aspects concerning the forecasts made for SC 23 maximum.
As regards the following cycle, in accordance to other early predictions, our empirical method,
based on observing the flare energy release during the descendant phase of the precedent SC,
estimate that the amplitude of SC 24 will be low.
1. Previous forecasts and a short review of SC 23
A large range of forecasting methods is used to predict the occurrence and ampli-
