When do solar erupting hot magnetic flux ropes form?
We investigate the formation times of eruptive magnetic flux ropes relative to the onset of solar eruptions, which is important for constraining models of coronal mass ejection (CME) initiation. We inspected uninterrupted sequences of 131 \AA\ images that spanned more than eight hours and were obtained by the Atmospheric Imaging …
