| Abstract: | The hybrid solar eclipse of April 8, 2005, provided a good opportunity to observe the white-light solar corona, even though
the eclipse lasted just 30 seconds and could be seen only from ships in the Pacific Ocean. During the eclipse, we detected
a unique ‘cloud’ of particles in the white-light corona above the west limb ≈260°–270°. We compare this feature with EUV images
from SOHO. The feature’s density and temperature seem comparable to a coronal condensation, and, like a coronal condensation,
it is connected to the emergence of material from the solar surface without a flare. However, the morphology of the feature
shows clear differences from a classical coronal condensation. |
