Continuous outflows in the active region that are rooted in Type-II chromospheric spicules.
In video taken by the NASA STEREO B spacecraft on Feb. 12 2009, we see the continuous, quasi-periodic, outflows in the active region that are rooted in Type-II chromospheric spicules. In this case, we see that, even though the active region erupts, the outflows do not stop.
