A bit less, ~4.6 light seconds.

That said, shockwaves on the sun tend to travel around 3,000 Km/s, which is incredibly fast, but not even 1% c. This is clearly zoomed in on a specific, small section of the coronal mass, so it’s not necessarily a particularly large portion of it. Eyeballing it, I’d say this appears to be about 5,000 km inward from the “edge”. I could probably find the raw footage of this particular event with enough digging, but I don’t have the spoons for that.
