A five frame sequence depicts a massive solar eruption, more than 30 times the length of Earth's diameter, blasted away from the Sun on July 1, 2002, and a satellite captured graphic images of the event. The eruption occurred at 13:19 GMT and showed up in a picture taken by one instrument of the SOHO satellite as a fiery-looking "leg" in the lower-left corner of the image, scientists said in a statement. The "leg" is what astronomers call an eruptive prominence, a loop of magnetic fields that trap hot gas inside. If eruptions like these are aimed at Earth, they can disturb Earth's magnetosphere, but this one was not directed at our planet, a spokesman for SOHO said. REUTERS/NASA/Handout

Satellite Pictures Show Huge Eruption on Sun

WASHINGTON (Reuters) - A massive solar eruption, more than 30 times the length of Earth's diameter, blasted away from the sun on Monday, and a satellite captured graphic images of the event.

The eruption occurred at 9:19 a.m. EDT and showed up in a picture taken by one instrument of the SOHO satellite as a fiery-looking "leg" in the lower-left corner of the image, scientists said in a statement.

 

Pictures taken over the following 90 minutes by another SOHO instrument show a loopy-looking eruption taking place and then dispersing. All images are visible at the SOHO Web site, http://soho.nascom.nasa ( news - web sites).gov.

 

The "leg" is what astronomers call an eruptive prominence, which is a loop of magnetic fields that trap hot gas inside. As this prominence became unstable, it erupted into the area around the sun and appeared to dissipate.

 

If eruptions like these are aimed at Earth, they can disturb Earth's magnetosphere, but this one was not directed at our planet, a spokesman for SOHO said by telephone.

 

SOHO -- short for Solar and Heliospheric Observatory -- is run by the National Aeronautics and Space Administration and the European Space Agency.

what the fuck is a magnetosphere?

 

Earth has a strong internal magnetic field. The forcing by the solar wind is able to modify this field, creating a cavity called the magnetosphere. This cavity shelters the surface of the planet from the high energy particles of the solar wind. Solar wind streams off of the Sun in all directions at speeds of about 400 km/s (about 1 million miles per hour). The source of the solar wind is the Sun's hot corona. The temperature of the corona is so high that the Sun's gravity cannot hold on to it.

 

So the concern with the magnetosphere is akin to concern with the ozone layer, since it protects us from harmful solar components
