General Description

Interferometric monitoring of the early phase of the Be star outburst.
 The aim of the project is to reveal the physivcal mechanism responsible for the
 outburst, in its phase when the mechanism is active and the mass is ejected to the
 circumstellar disk.
The last OB, carried over from P82 should be executed in nthe very end of September
 and in the end of the night, when inner disk is expected 
to develope and to be detectable by AMBER.

Waiver Requests

Because the target is very bright, no finding charts need to be submitted.
 In fact, for the UVES requested FOV the target fills most of the finding chart in
 the SkyCat image.

Critical Observing Condition Constraints

```
none
```

Time-Critical Aspects

The OB should be executed in the second half of September 2009.

There is no UVES OB left to be executed simultaneously with AMBER in P83.

Special Execution Requirements

The baseline configuration A0-K0-G1 is preferable, and the ST constraints
 are derived for this configuration (DL restriction for A0-K0).
Configuration A0-D0-H0 is acceptable, if ther is no chance to get the A0-K0-G1 configuration.

OB names: SCI[CAL]_star-name_epoch


HD47536 calibrator should be executed before the SCI OB.

Do all your OBs comply with the instrument-specific requirements listed on the instrument-specific Phase 2 web page ?

If this is a pre-imaging run, did you select PRE-IMAGING for the Observing Category for each Observing Template ?

Do all your finding charts comply with both the general and instrument-specific Phase 2 Web Pages ?

If you submitted OBs for standard stars, did you specify the magnitude and spectral type of all standard stars in the OBs ?

Have you included OBs for any calibrations that you need but which are not part of the Calibration Plan ?

If you are observing Moving Targets, have you attached suitable ephemeris files to your OBs?

If you have preferences which OBs should be executed first, did you make use of the User Priority field in the OBs ?

If this is a run that requires coordinated observations with other facilities, did you give proper instructions in the Time-Critical Aspects Section ?

Did you indicate for each science star OB the corresponding calibrator star OB (and vice versa) in the 'Instrument Comments' field ?

Did you check that your chosen calibrator is bright enough for the instrument mode used ?

If you use calibrator stars which are not in the CalVin database, did you specify their characteristics in the README file and in the OBs ?

Do you use the same DIT for pairs of science target and associated calibrator?

Are the magnitudes of science target and calibrator within +/- 1 mag ?

Did you verify that your coordinates are as accurate as possible (2Mass coordinates recommended) and that they include proper motions if available ?

Did you specify the LST range of the calibrators such that they cover the range from 30 min before the start of the LST range of the science target to 30 min after the end of the LST range of the science target ?
