H-alpha viewing of flare and seeing start of CME?

[cathalferris]

I've subscribed to one of the online email alert services for solar flares. Luckily I was at home when one cracked off a little while ago, so I broke out the PST for a quick look.

I could quite easily see the flare beside that large convoluted spot that's there at the moment.

However, when I was tuning the view, I noted a dark streamer heavily blueshifted coming from the flare source. I could follow that dark streamer across the disk for quite a turn of the tuning ring, right through until I could no longer see any prominences - looked like a white-light view except for this dark streak.

Tl;dr is don't be afraid to tune well outside the sweet spot with H-alpha scopes, as you may get to see really fast moving stuff.

Tuning 'in and out' is always part of the interest for me. It's amazing how different features come out in the process.

What was interesting this time for this particular feature is that it was still visible when I was tuning to the end of the available rotation on my PST. Moving really really fast towards us!

Do we have to take cover ...? :-)
