Original abstract

The hybrid solar eclipse of April 8, 2005, provided a good opportunity to observe the whitelight 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 whitelight corona above the west limb 260deg to 270deg. We compare this feature with EUV images from SOHO. The feature 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.
