Abstract :
HF radio and magnetic field changes were the first space weather problems experienced. Worldwide magnetometer and ionosonde networks were developed to better understand the problems and advance practical advice. The Ionospheric Predictions Service (IPS) was formed to co-ordinate Australian ionospheric monitoring and advise HF communicators and other groups interested in the effects of solar activity. Although customer numbers and sophistication have changed, service demand has remained steady. Currently, IPS distributes realtime services for HF radio, magnetic and space customers through the web (http://www.ips.gov.au) in addition to other conventional services. The Web HF services are based on an empirical ionospheric model updated hourly using ionosonde data. Magnetic services use similar, empirical, data-driven models.
