  • 22 November 07 Massive depressions to usable HF frequencies are currently being experienced throughout the Southern Hemisphere. A T-index of -82 was calculated for the Australasian region. The massive reductions in usable HF frequencies relative to those expected for the current time of year and solar cycle are the uncommon result of particularly low levels of ionising radiation combined with a recent major geomagnetic storm. On 20 November geomagnetic and aurora alerts were issued by IPS indicating major geomagnetic activity. Ionospheric depressions are very common following a major geomagnetic storm.  


  • 22 March 07 Further HF Radio Propagation Courses will be conducted in Melbourne and Hobart on 17 and 21 May, 2007. The one-day course will enhance understanding of HF radio propagation, explain the space-weather environment and increase the value of the IPS HF prediction and management services to our customers. Follow this link for further details.    


  • 20 March 07 An HF Radio Propagation Course has been scheduled for 10 May, 2007 in Perth. The one-day course is designed to enhance understanding of HF radio propagation and the space-weather environment and to increase the value of the IPS HF prediction and management services to our customers. Follow this link for further details.    


  • 20 March 07 IPS has improved the ionospheric foF2 (vertical MUF) plot with larger graphs for each station, and inclusion of the ionospheric foF1 parameter.    


  • 21 February 07 An HF Radio Propagation Course has been scheduled for 19 April, 2007 in Canberra. The one-day course is designed to enhance understanding of HF radio propagation and the space-weather environment and to increase the value of the IPS HF prediction and management services to our customers. Follow this link for further details.    


  • 20 November 06 Tonga Hourly HAP charts have been made available on the IPS website. Tonga Hourly HAP charts are based on currently observed ionospheric conditions in the Tonga region, updated hourly. Regions with Hourly HAP availability can be selected from the drop down menu after following this link.    


  • 09 November 06 HF Spectrum monitor at Culgoora Observatory. A HF spectrum monitoring system has been installed at IPS Culgoora Observatory, near Narrabri, northern NSW Australia.   


  • 2 November 06 Real-time Hourly HAP Charts now available for Fiji. Fiji Hourly HAP charts have been made available on the IPS website. Fiji Hourly HAP charts are based on currently observed ionospheric conditions in the Fiji region, updated hourly. Regions with Hourly HAP availability can be selected from the drop down menu after following this link.
