Giant solar Filament erupts on the sun 18th October 2010

A gigantic solar "filament" erupted on the sun on the 18th on October.
According to Spaceweather - For days, astronomers had been monitoring the "mega-filament" of magnetism splayed across the sun's southern hemisphere. Measuring more than 500,000 km from end to end, it spaned a distance greater than the separation of Earth and the Moon before it erupted:

Posters comments:
Around 16:00UT (12:00 EDT), the giant filament next to sunspot group, AR11112, produced a small eruption along with a small C2.5 solar flare. Some type of instability in the magnetic field over the filament caused part of the hot solar plasma making up the filament to be released sending some of the material into space. This video show the eruption with data from the Solar Dynamics Observatory (SDO). The video shows 4 wavelengths of extreme ultraviolet light, 304, 171, 193 and 211 Angstroms. A small narrow feature, possibly a CME (coronal mass ejection), can be seen moving outward from the lower right in the LASCO C2 coronagraph. But it does not appear to be earth directed.

Why the quotes around the word "filament?"(See, here it is applicable because I am quoting a specific word for reference)When you place quotations around a single word in a sentence, it usually you are either making reference to the word itself (like in the sentence above) or questioning the use of the word. Consider these three examples:

1) "Giant" solar filament erupts on the sun.
2) Giant "solar" filament erupts on the sun.
3) Giant solar filament "erupts" on the sun.
4) Giant solar filament erupts on the "sun."

Do you notice that when you read them, they actually mean different things, depending upon the word placed in quotes?

Using this logic, which is standard grammar, you seem to be questioning both the terms "filament" and "mega-filament" in your post. Why?

That's what they are called. Just like the sun is a star and the earth is a planet and when volcanoes erupt they spew out this stuff called lava.

In this case, the event in question is a solar filament and even more precisely, a mega-filament.

It reduces your credibility when you question standard nomenclature like this and takes your post from reporting an interesting astronomical event down to conspiratorial kookiness.

To: [VirtuallyLucid]...Your comment was helpful, and quite clear, but in my humble opinion,I think the quotes around the word; "filament" was to bring attention to the word! at least,that was the way I saw it,because some people, might not know what a gigantic solar "filament" erupting on the sun, might be!?........thanks!
