Query: The Double-Bubble CME of the 2020 December 14 Total Solar Eclipse   Total solar eclipses (TSEs) continue to provide an invaluable platform for
exploring the magnetic topology of the solar corona and for studying dynamic
events such as Coronal Mass Ejections (CMEs) -- with a higher spatial
resolution over a larger spatially continuous extent than is possible to
achieve with any other method at present. In this Letter, we present
observations of the full extent of a `double-bubble' CME structure from the
solar surface out to over 5 solar radii, as captured during the 2020 December
14 TSE. Its evolution through the corona was recorded from two observing sites
separated by 13 minutes in their times of totality. The eclipse observations
are complemented by a plethora of space-based observations including: Extreme
Ultraviolet observations of the solar disk and low corona from SDO/AIA and
STEREO-A/EUVI, white-light coronagraph observations from SOHO/LASCO-C2, radio
from STEREO-A/WAVES and WIND/WAVES, and X-ray from GOES-16. We also
characterize the magnetic field with a potential field source surface model.
This CME event itself is of particular interest, as it demonstrates
interactions between a prominence channel and an active region that led to the
double-bubble structure. Despite the plethora of space-based observations, only
the eclipse data are able to provide the proper context to connect these
observations and yield a detailed study of this unique CME.
