General Description

Multi-epoch VISIR+MIDI+AMBER observations of the carbon-rich Mira star
 R For.  This run represents the second epoch VISIR observation.   The observation
 should be carried out at two perpendicular slit orientations to probe possible deviation
 from spherical symmetry in the dust shell.  The VISIR and MIDI data will be used
 for deriving the physical properties of the dust formation zone and for better unterstanding
 the dust condensation sequence in carbon stars.  The OBs in this run should be executed
 as close in time as possible 
to the other MIDI/AMBER runs for the second epoch, i.e., 080.D-0231(G), 080.D-0231(H),
 080.D-0231(I), and 
080.D-0231(J).  The finding chart is a Ks-band image, and the object is the brightest
 source in the N band in the field of view of VISIR.

Waiver Requests

No Waiver Request was submitted

Critical Observing Condition Constraints

All OBs should be carried out in CLEAR sky condition with seeing better
 than 1" and airmass smaller than 1.5.

Time-Critical Aspects

The OBs should be carried out in December 2007.  However, if some OBs
 cannot be executed in this period, it is also acceptable to carry them out in later
 months.
