Huge Solar Eruption
It is not threatening, but it is still an extraordinary sight. In time we will collect a large library of separate events that will be well worth speculating on and possibly modeling. Perhaps some day we will even model the twists and moves taking place inside the sun itself. I do not expect to develop accurate forecasting for anything but the gross events like sunspots which may well become much more predictable.
I think the speed of change is just too chaotic. The appearance of form and shape is in practice likely to be simply misleading.
Otherwise enjoy this clip.

This video by NASA’s Solar Dynamics Observatory captures a dramatic filament eruption on Aug. 31. Shown in the video in extreme ultraviolet light, the filament collapsed and exploded in spectacular fashion. The segment shown in red covers nearly 3 hours.
The NOAA spaceweather prediction center estimates the resulting cloud of radiation will reach Earth on Sep. 3, but will only create a minor to moderate geomagnetic storm.
