General Description

InterferoInterferometric monitoring of the early phase of the Be star
 outburst, which 
is supported by the spectroscopic UVES observations. The aim of the project 
is to reveal the physical mechanism responsible for the outburst in the phase, 
when the mechanism is active and the mass is ejected to the circumstellar disk.

Critical Observing Condition Constraints

Because the target is very bright, no finding charts need to be submitted.

Two calibrators per one calibrated point, it is one calibrator to be executed 
before and the second after the science target, in order to increase the 
accuracy of the absolute calibration. The higher accuracy is required for the detection
 of the new inner circumstellar disk.

Time-Critical Aspects

AMBER observations should be coordinated with the UVES monitoring - still
 2 OBs
in the UVES B queue. Observations do not need to be exactly simultaneous, execution
 
of AMBER/UVES ONBs within 1-2 days is sufficient.

Special Execution Requirements

AMBER observations should be coordinated with the UVES monitoring - still
 2 OBs
in the UVES B queue.

Ideally 2 observations of the same epoch should be executed during the same 
night and the separated as much as possible in hour angle, however the 
execution during a few days is exportable, if possible with E1 at the beginning
 
of the night and E2 as much as possible separated in HA.

Special Calibration Information

12 submitted OBs for 4 calibrated visibility points. Each calibrated point
should be a sequence:
CAL_HD47536_Mar_Ex_HAx  -   SCI_28CMa_Mar_Ex_HAx  - CAL_HD64974_Mar_Ex_HAx
it is the calibrator HD47536 should be always executed before the science 
target, the calibrator HD64974 after the science target.

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 ?

```
N/A
```

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 ?
