211 Isolda is a very large, dark Main belt asteroid. It is classified as a C-type asteroid and is probably composed of privitive carbonates.

OCCULTATION BY (211) ISOLDA - 2005 AUG 02
On 2005 Aug 02 UT, the 143 km diameter asteroid (211) Isolda will occult a 12.3 mag star in the constellation Sagittarius for observers along a path across Australia stretching from northern New South Wales near the Queensland border to Shark Bay, Western Australia.
In the case of an occultation, the combined light of the asteroid and the star will drop by 1.1 mag to 12.9 mag (the magnitude of the asteroid) for at most 11.0 seconds.
