General Description

This is a standard MIDI observation of the FU Ori object V 1647 Ori. To
 calibrate the data an observation of HD 37160 afterwards is required. Since the
 sciene target is faint in the visual and no guide star is available, MACAO cannot
 be used. Therefore, the calibrator has to be observed without MACAO too, because
 the influence of MACAO on the instrumental visibility has not been fully investigated.

This is run D. The other runs are A and B.

Waiver Requests

No Waiver Request was submitted

Critical Observing Condition Constraints

The seeing should be better than 0.6''(?), because MACAO cannot be used.

Time-Critical Aspects

The OBs of this run should be executed at least one month after the OBs
 of run B. Longer periods between the two runs are preferred. However, in the case
 of unexpected problems, the highest priority should be given to the purpose to execute
 both runs.

Special Calibration Information

Standard MIDI calibration. Please observe the calibrator HD 37160 like
 the science target without MACAO.

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 ?

```
N/A
```

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?

```
N/A
```

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

```
N/A
```

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

```
N/A
```

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

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 ?
