Solar Tsunami

NASA’s Solar Dynamics Observatory captured high definition views of the SUN at a variety of wavelengths and snapped an X-ray photo of the Sun, on Sunday, august 1st 2010.

A dark arc was recorded by the satellites and identified as a large filament of cool gas extending towards the SUN’s northern hemisphere and exploded in the space.

This explosion is called as Coronal mass ejection and was aimed directly to the Earth, which immediately sent a “solar tsunami” racing at 93 million miles athwart space. This solar Tsunami reaches the Earth’s magnetosphere and may cause the geomagnetic storms.

Usually the SUN’s activity recedes on a fairly predictable cycle. Normally one cycle lasts for 11 years, roughly taking five and half years to move from a solar minimum, the period when we can find few sunspots, to peak at the solar maximum, when the activity of sunspot is amplified.

The final solar maximum occurred in 2001, which was weak but lasted long. The recent solar eruption is a sign that the sun is waking up and going towards another maximum. Experts said that when it touches the magnetic shield, it is likely to flash fabulous displays of the aurora or southern and northern lights.










Solar Tsunami that lasted for 35 minutes in the year 2007. The same thing happened again on 3rd August 2010.
