After some puzzling early convolutions and a lengthly pause between +7m and +27, this filament rushed to a height of 136Mm, a further 70Mm in 6 minutes, about 200km/s. This is a fairly typical ejection velocity, but solar escape velocity is over 600km/s. Having reached that height it rapidly fell back to its start point. After peak height it lost much of its earlier brightess - it was about 50% chromospheric brightness at peak height.
