Magnetic Eruption on 14 December 2010


MAGNETIC ERUPTION : On Dec. 14th around 1530 UT, a filament of magnetism lifted up from the surface of the sun and--snap!--erupted. NASA's Solar Dynamics Observatory recorded the action.
The blast produced an hours-long C2-class solar flare and hurled a magnificent CME into space: SOHO movie. The expanding cloud is not heading directly toward Earth, but it might deliver a glancing blow to our planet's magnetic field two or three days hence. High latitude sky watchers should be alert for auroras.

89 Instruments used for tank test on Discovery

Shuttle Discovery's tanking test will occur no earlier than Friday as cold weather and strong wind have slowed preparations.

Workers at launch pad 39A at Kennedy Space Center continue to instrument the tank with temperature sensors, after work through the weekend finished attaching strain gauges.

In total, nearly 90 instruments are being placed on the tank's mid-section. Fresh insulating foam will be applied over those areas.

The sensors won't bond properly to the tank's metal skin in cold weather. Specially constructed environmental enclosures and thermal blankets are being used to control temperatures.
