High-frequency communications, or HF, is an essential tool used across the globe, especially on the African continent, for long-distance communications. An example of this was during the Mozambique hurricane disaster when cell phone systems became overloaded and satellite phones did not
The past two days (5–6 November 2023) have seen a ramp-up of the Sun’s activity. Earth experienced a slew of geomagnetic storms over the weekend, ranging from G1/Minor (Kp 5) to G3/Strong (Kp 7). The storms were a result of
A severe geomagnetic storm caused by a coronal mass ejection (CME) from the Sun arrived late on Thursday 23 March and continues to impact the Earth and its technological systems today. The CME was ejected from the Sun on Monday 20
New research [1] predicts that the new solar cycle (SC25) is going to be stronger than initially expected. It is now believed solar cycle (SC25) will be at similar intensity as SC23 which brought us the famous Halloween Storm of
High-Frequency communications or HF is an essential tool used across the globe and especially on the African continent for long-distance communications. Many sectors across the continent rely greatly on HF communications for different purposes. Such sectors include the Aviation, Disaster Management,

A dark filament of a wound-up magnetic field erupted from the Sun's southern hemisphere on 19 September. It is not directly headed for the Earth, and when it arrives on 23 September, it may not have a significant impact on
International Space Weather Camp This is a once-in-a-lifetime opportunity for students to learn all about space science and technology with a focus on space weather, a relatively new and exciting field involving the study of the Sun and its influence on
A new High Frequency Digital Radar will be unveiled at the final World Space Week event for SANSA this year at a ceremony on 9 October 2013 in Hermanus, Western Cape. The radar system forms part of the Super Dual
