Purpose of the flight and payload description

A balloon-borne instrument to make measurements of the cosmic microwave background (CMB) anisotropy on angular scales between 0.5 and 3 degrees. The experiment uses a one meter, off-axis Cassegrian telescope, coupled with a four spectral band radiometer. The pointing for the experiment is controlled by a platform which was originally built in the early 1980's by a group at GSFC to map the Galactic plane (FIRS instrument).

This second flight was intended to make observations of the same region of sky than in the first flight. It produced a measurement in statistical agreement with the 1992 observation.
