General Description
This programme studies the feasibility of using VLTI for studying starspots on the stellar surface. The interferometric observations are compared to the contemporaneously constructed stellar surface temperature maps obtained from the UVES spectra, thus the AMBER and UVES observations should not be separated by more than three weeks (~1 stellar rotation). And the 10 UVES observations should be evenly spread over the 3 week stellar rotation period. Possible dates for the observations are given in "time critical aspects". Please, in very good seeing conditions check that there is no saturation in the red part. Note also that the instrument setup has been changed from slit to image slicer (approved by USD).

Critical Observing Condition Constraints
No critical observing conditions: thin clouds, seeing < 2.0, airmass < 3.0, no restriction on the Moon phase

Special Execution Requirements
The 10 observations should be evenly spread over the stellar rotation, thus each OB has a certain time window when it can be executed. The possible dates are given in the time critical aspects.
