General Description

MIDI observations of the silicate carbon star BM Gem with 3 different
 baseline configurations.
The scientific goal is to detect the presence of a circum-companion disk and derive
 its
physical properties by combining with its VISIR spectrum and radiative transfer
 modeling.
It will help us to understand the origin of silicate carbon stars.

Note that the calibrator HD48433 (V=4.5) is a double system with a fainter companion
 (V = 11) 
at a separation of 27" and a P.A. of 184 deg, which cannot be seen in the finding
 charts 
because of the saturation of the brighter component.  But the calibrator to be observed
 
is this brighter star, and its coordinates are given in the OBs.
