I saw something on the Sun today that I had never seen before (although, I've only ever looked at it a handful of times). A prominence kind of detached itself and started to kind of... float away... from the Sun.
I just thought it was kind of cool.

It looked a bit different in the telescopes I was looking through, but they're not nearly as big as the one used to take this picture. :P
What do you mean, reconnected?

Right. That's so cool. The Sun's magnetic field is amazing.

What filter did you observe it through? Hydrogen alpha?

Yes
There were also a couple scopes using white light filters.
but I didn't see the prominence activity through those. :P

about 4 visible, one at the edge of the limb and three on the Western hemisphere
about average for this part of the cycle I guess

Yeah, that's about what I've been seeing every time they do these.
