Monthly Meeting: Mr. Sam Walton – “Space Weather”
Friday, 17th September 2021 @ 19:00 - 21:00 BST
The September 2021 monthly meeting of Liverpool Astronomical Society will be held on Friday, September 17th from 19:00 to 21:00.
Our guest speaker this month is Mr. Sam Walton, of the Space Plasma Physics Group, in the Department of Space & Climate Physics, in the Mullard Space Science Laboratory at University College London, whose lecture is entitled:
The Sun is an essential ingredient for life on Earth, providing light, energy and warmth, however it is also a huge danger to us. The Sun continuously ejects millions of tonnes of highly energetic, electrically charged particles into space, known as the ’solar wind’.
When the solar wind reaches Earth, it interacts with our planet’s geomagnetic field in extremely complex ways, posing a danger to technological infrastructure such as satellites, power grids and communications. We call this phenomenon ’Space Weather’.
This talk will guide you through the origins and journey of the Solar Wind from the Sun to the Earth, describing some of these complex interactions and why they are so threatening to our existing infrastructure. Finally, what are scientists doing in order to ultimately understand, predict and mitigate the effects of space weather?
Please note, due to COVID-19 this meeting is ONLINE-ONLY.
Society members have been sent Zoom & YouTube links.

With best wishes – Mark
