Another question but about the filaments

[Isatsuki San]

Sorry if you disturb, I want to ask about the solar filaments, if a long filament erupts, what could it cause against the earth? In addition to a cme, are fillamentros if erupting dangerous?

Filament eruptions can cause a CME. A part of the material comes back on the sun after the filament eruption, phenomenon known as coronal rain. Some big filament eruptions can cause a strong geomagnetic storm on Earth but nothing serious. 
also it gives superb imagery on LASCO and other great shots from SDO.

There's an interesting "something" extending from the solar disk past the SE limb.   Figuratively, it looks like an elephant's trunk or a tornado.  Yet to be seen whether it will detach or recede back into the sun.  In its present state, would this be called a filament or a prominence?

It’s a nice filament that would give nice images if it snaps. 
ps: if it’s a loop, it’s a prominence; if not it’s a filament 😉

Las erupciones de filamentos pueden causar una CME . Una parte del material vuelve al sol después de la erupción del filamento, fenómeno conocido como lluvia coronal. Algunas grandes erupciones de filamentos pueden causar una fuerte tormenta geomagnética en la Tierra, pero nada grave. 
también brinda imágenes excelentes en LASCO y otras excelentes tomas de SDO .

Muchas gracias por contestar, de verdad siempre  agradezco que me contestes
