TVs around the world could go on the blink during the 2012 London Olympics, solar physicists warned today.
世界各地的電視可能在2012年倫敦奧運會時期不斷閃爍，太陽物理學家今天警告。
They were speaking ahead of the launch of the Solar Dynamics Observatory (SDO), which will blast off on February 9.
他們在發射太陽能動力天文台(SDO)之前講出，它將在2月9日升空。
Nasa's latest space mission will deliver high resolution images of the Sun ten times better than the average High-Definition television.
NASA的最新太空任務，將傳送太陽的高解像影像，比平均高清晰度電視 好10倍。
UK scientists are gearing up for the launch of Nasa's Solar Dynamics Observatory. This will deliver high resolution images of the Sun英國科學家正在準備好為NASA發射的太陽能動力學天文台，這將可傳送太陽的高解像影像
A picture using extreme ultra-violet light will be snapped every 0.75seconds. In a day the satellite will transmit the equivalent amount of data as 500,000 song downloads. It will produce more science data than any mission in Nasa history.
British scientists involved in the project said the observatory could help them predict solar storms that could disrupt communications on Earth.
參與該項目的英國科學家指出，天文台可幫助他們預測太陽風暴，它們可能會破壞地球上的通信。
This could prove crucial as solar activity is due to hit a peak in its eleven-year cycle during the Olympics in 2012.
這可以證明至關重要，因為太陽活動的11年週期在2012年奧運會期間，到期達到高峰。
Professor Richard Harrison from the Rutherford Appleton Laboratory in Oxfordshire, told the Mail Online: 'The Sun's magnetic field is all over the place and huge clouds of energy escape from time to time in coronal mass ejections.
'These can carry a billion tonnes of solar material into space at nearly a million miles per hour. Such events can disable satellites, cause power grid failures on Earth and disrupt communications.'
By studying the Sun in greater detail, scientists are hoping to be able to predict and better prepare for disruptive solar activity (seen here in ultra-violet light)更詳細地研究太陽，科學家們希望能夠預測和更好地為破壞性的太陽活動作準備（透過紫外光在這裡看）
He added: 'Our Sun is just coming out of a deep minimum, which is a period of very little activity. Whether this means we will have an unusual maximum in 2012, we just don't know.
'What is certain is the chances of general disruption will be far higher during this period and could disrupt coverage of the Olympics.'
Professor Harrison said missions like the SDO couldn't prevent solar activity, but could help people to prepare for them. Companies could be told in advance to switch off vital satellite circuits and technology systems could be improved on Earth.
'It's like predicting the rain,' he said.
'You can't stop it but if you know it's coming you can put an umbrella up.'
Engineers from the Rutherford Appleton Laboratory have also built the electronics systems for the six cameras on two of SDO’s instruments. These will control and read out the huge amount of data.
Project manager Sarah Beardsley, from RAL, said: 'Space missions require extremely light and compact, power-saving equipment which has to be built to stringent design and manufacturing requirements.
'The design of the electronics boxes has been so successful that we are now under contract to design and build the camera electronics for an instrument on Nasa's forthcoming GOES-R weather satellite.'
The Solar Dynamics Observatory (SDO) has four AIA telescopes, which are at the top. The solar arrays will collect energy from the Sun to power the spacecraft. EVE measures the tumultuous solar emissions, while the HMI will measure the magnetic field on the visible surface of the Sunhttp://www.dailymail.co.uk/sciencetech/article-1248012/Solar-storms-disrupt-2012-Olympics-warn-scientists-new-satellite-help-predict-whats-coming.html
