Unstable solar filament erupts stretching itself out almost 700,000 km long

That’s an extraordinary stretch!

Watch this unstable filament of magnetism rise up, erupt and stretch itself out almost 700,000 km long from the sun’s eastern limb. Awesome!

The magnetic loop kept going … and going… until it stretched itself out almost 700,000 km long. Here another view of this giant elongation!

The prominence was half the diameter of the sun and twice as long as the distance between Earth and the Moon.

David Strange – what a name! – also captured the extraordinary stretch:

As well as French astrophotographer Sylvain Weiller:

Part of the prominence snapped off and formed the core of a bright CME. The expanding cloud billowed away from the sun’s eastern limb, well off the sun-Earth line, and is not expected to hit our planet.
