โœฆ Synopsis

The Babcock "solar dynamo" model and known interactions of the interplanetary magnetic field with the earth's magnetosphere are used to explain the relations found between geomagnetic indices at solar minimum and the sunspot number at the following solar maximum. We augment the work of Kane (1987) by updating his method of analysis, including recent smoothed aa and A_ indices. We predict a smoothed maximum sunspot number of 163โ€ข Go peak in October 1990โ€ข months for solar cycle 22. This value is close to the Schatten and Sofia (1987) predicted value of 170โ€ข using more direct solar indicators.

## Abstract The delayed release of the National Account data for GDP is an impediment to the early understanding of the economic situation. In the short run, this information gap may be at least partially eliminated by bridge models (BM) which exploit the information content of timely updated month
