Scientists warned yesterday that a peak in solar activity is due to occur in 2012, risking the disruption of television and internet networks during the London Olympic Games.
“The Olympics could be bang in the middle of a solar maximum,” said Richard Harrison, of the Rutherford Appleton Laboratory, Oxfordshire, speaking before the launch this week of Nasa’s Solar Dynamics Observatory.
It has long been known that surges in solar activity can cause disruption in satellite and terrestrial communications systems, but, until now, it has been almost impossible to predict solar storms in advance.
After the launch of Nasa’s solar observatory, scientists say that they will be able to give warning of magnetic storms and solar flares.
