Welcome to the Southern African Space Weather and  Ionospheric Information home page. Here you will find information on the ionosphere over Southern Africa and other relevant South African Space Weather information. Any comments or suggestions can be sent to the Regional Warning Centre for Africa at rwc@hmo.ac.za.

If you are new to space weather, please click here for an introduction to the subject.

Get the latest space weather conditions and  predictions here. Or, if you are interested in the magnetic and ionospheric data for the region, go to the HMO space weather site here.

CURRENT CONDITIONS: Geomagnetic conditions are at quiet levels. Local HF working frequencies are unstable to slightly depressed from predicted monthly average values.

OUTLOOK:  Propagation conditions should be fair, with unstable values from predicted monthly average HF working frequencies.

.The Latest Info page will keep you updated and provides a table containing three-day predictions of various Ionospheric and HF-related factors, as well as a graphic representation of predicted SSN and Geomagnetic values for the next 103 days. The latest Ionograms from Grahams Town, South Africa (1hr update vertical incidence), Louisvale and Madimbo, South Africa, are also shown on this page, when available. Solar information for the past 30 days is also provided in graphical form. This page also contains links to Monthly and Daily T-index predictions as well as past-30-day information of of solar and magnetic parameters

Bulletins will provide you medium-term predictions of daily SSN and Qfe values, also a link to the new Daily T-Index predictions page, as well as the latest monthly T-indices from IPS. Space-weather conditions predictions (last update dates are provided with the bulletins), as well as weekly average Wind Corrected Indices (WCI), Qfe and weekly average T-index  predictions are also provided. The latest Southern African Ionograms are also provided on this page.

Daily Frequencies: This page contains daily MUF, LUF, Optimum Working Frequency and Take-off angle predictions between Cape Town and Pretoria, Cape Town and Durban, as well as between Pretoria and Durban - in addition to any special requirements lower down on the page.

bullet

Service for Radio Amateurs: This page contains frequency predictions on the HAM radio bands from central South Africa to most continents and between various regions within South Africa.

Products will be your guide to what PST can do to help you improve your HF communications - permanently under construction.

Some very interesting links to other sites can be found here.

Below are the latest images from The SOHO Extreme ultraviolet Imaging Telescope brought to you by The EIT Consortium when available. Full resolution versions of these images can be found at the  SOHO spacecraft web site, or by clicking on the images below. The "CCD Bakeout" text that sometimes appear on these images refer to a regular (about once every 5 weeks) maintenance procedure performed on the SOHO satellite. This normally takes about a week, but about 20 days every three months.
