Main Scientific Program
Observation of fine structures in the disks and
jets around a sufficient number of Young Stellar
Objects Observation of the dust tori and of
the Emission Line Region of the brightest Active
Galactic Nuclei Measurement of the low
resolution spectra of Jupiter like planets
orbiting up to 0.1 a.u. away from a solar type
star at 10 pc distance

Commissioning 2 (Oct. 2004)

• Stability of the instrument hardware OK after
  a few months without observations
• Routine operations in low spectral resolution
  in the H and K bands (siderostats UTs)
• and in medium spectral resolution in the K
  and H bands (UTs).
• Three telescope observations OK.
• Instrumental transfer function close to 1 with
  excellent atmospheric conditions.
• Limiting magnitude of AMBER in medium
  resolution K about 6.
• Issues remaining to be tested and checked
• Identify all sources of vibration of the VLTI.
  Corrective actions are being taken.
• Better VLTI baseline model required to evaluate
  the AMBER limiting magnitude in low spectral
  resolution.
• Optimization of the entrance flux and interface
  with the new VLTI IRIS image sensor.
• Test of the differential OPD between bands and
  Atmospheric Dispersion Compensator.
• Simultaneous fringe search with 3 telescopes.
• Interface with the FINITO fringe tracker.
• Performance assessment with the ATs.
• Improve the alignment maintenance modifying
  some mechanics.
• Next commissioning run on sky beginning of
  period P75 (starting April 2005).
• Science Demonstration Time and Guaranteed Time
  Observation with 3 UTs Christmas
