The solar cycle, eruptions from the Sun and their consequences for Earth ROYAL ASTRONOMICAL SOCIETY'S LONDON DISCUSSION MEETING ON MARCH 9TH

The Sun is far from being a remote, unchanging source of light and warmth. Rather, we live within the outer atmosphere of a variable star. The one-day discussion meeting on 9th March, in the Royal Astronomical Society's regular monthly programme, focuses on the results of recent research into the energy flowing from the Sun to the Earth and the consequences for our planet of the Sun's variability.

Media representatives are welcome to attend. The meeting is in the Geological Society Lecture Theatre at Burlington House, Piccadilly, London, W1.

MORE ABOUT THE TOPIC OF THE MEETING 

Recent discoveries have led to new insights into the relationship between the Sun and the Earth and to a new appreciation of the effects of solar activity on the Earth and human activities. This meeting is taking place  just after the peak in the 11-year solar activity cycle and draws together the results of recent studies of solar activity, such as solar flares, coronal mass ejections, the 11-year solar cycle and even longer-term variations. The speakers include many of the leading figures in the field of solar-terrestrial physics, as well as younger researchers, presenting results that trace the effects of solar activity from their origins on the Sun, through interplanetary space and their interactions with the Earth.

The highlights of the meeting include reviews of the most recent investigations into the link between solar flares and coronal mass ejections and their interaction with the Earth's magnetic field and upper atmosphere, as well as the effects of solar activity on man- made systems (such as power grids and spacecraft) and its role in climate change. Prof. Mike Lockwood will talk about important investigation into the effects of long-period solar changes on climate and the implications for interpreting climate change
