The SWS Daily Solar and Geophysical Report provides a one day summary and three day forecast of solar activity, geomagnetic activity, global HF propagation conditions and ionospheric conditions in the Australian region.
Solar summary information is predominately obtained from the US Space Weather Prediction Centres (SWPC) Report on Solar and Geophysical Activity (RSGA) as this report covers overnight activity. Recent, and current local day activity is reported from the IPS Culgoora Solar Observatory and the joint USAF/IPS Learmonth Solar Observatory (both as images and text reports). The US SWPC's RSGA is available at: US SWPC Report on Solar and Geophysical Activity Both the US SWPC and IPS are members of the International Space Environment Service (ISES). The ISES website is at: ISES home page. ISES is a international body through which Regional Warning Centres co-ordinate the exchange of space weather data. The SWPC operates the RWC Boulder, and SWS operates RWC Sydney. There are many RWCs around the world.
Solar imagery is used from around the world and from space based observation. A list of ground and space based observatories is available Solar observatories
Geomagnetic summary information is obtained from a network of SWS magnetometers. K indices are generated from the magnetograms. Forecasts are a subjective assessment based on recent solar coronal mass ejection activity, Type II and IV radio sweeps and 27 day recurrence patterns. For more information on K indices see the SWS Help Page at: SWS Geophysical Help Page
Global ionospheric conditions are simply inferred from current and expected geomagnetic conditions.
Ionospheric summary information is based on a network of ionosondes operated by SWS which provide vertical maximum usable frequency measurements of the regional ionosphere. This allows both a text summary of the level of support to be generated and an ionospheric index, the T-index to be calculated. The 3 day forecast of the ionospheric support level bascially follows the forecast of geomagnetic activity, with lower levels of ionospheric MUFs expected following days of increased geomagnetic activity.
Ionograms and autoscaled data are freely available in near real time on the SWS website at: SWS HF Systems Section
The SWS World Data Centre is the long term data store for the data that the Australian Space Forecast Centre uses in near real time. The World Data Centre is at: SWS WDC Home Page Solar images, magnetometer data and ionograms are available in the SWS WDC.
Background reading on space weather is available at: SWS Educational Pages
