Programs 74.A-9006(A) and 74.A-9006(B) are a common program to determine
of a large number (few hundred) of young Brown Dwarfs and low mass stars
in the Orion Nebular Cluster (ONC) the rotational period in order
to study the angular momentum evolution of these objects.

Program  74.A-9006(B) is the "core". This program has to be carried out
in the 4 nights from Nov. 29./30. -- Dec. 2./3. 2004.
In each of these 4 nights the ONC is continously observed for 6 hours.
This "core" of the program is important for determining the rotational
periods of the rapid rotators in the ONC (P <~4 days).

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
(6 domeflats for each night of observations), skyflats (2 OBs)
and darks (1 OB). All submitted OBs have suggested date of its execution
included in their names.
