	    At least one image of the of ChaI-DC in each MPG-night.
 
Program 74.A-9017(A) and 74.A-9017(B) are a common program to determine
of a large number (~100) of young Brown Dwarfs and young low mass stars
in the ChaI dark cloud (ChaI-DC) the rotational period in order
to study the angular momentum evolution of these objects.

Program  74.A-9017(B) is the "flanking" part of the program which is very
important for  determining  periods much longer than 4 days. Therefore
it is planned to take in practically all other  MPG-night at least
one image of the of ChaI-DC.

The program should be carried out even under very poor conditions!
It should be possible to get still useful information on the brighter
stars and on a highly variable objects, even if they are faint.

To support non-standard filter PI submitted OBs for domeflats,
skyflats and darks. All submitted OBs for flats have suggested date of its
execution included in their names.
