General Description

MIDI observations of the nova V1280 Sco.

The set of OBs is exactly identical to the set 278.D-5053(B) that provided successful
 observations with the baseline G0-K0, close the limit of sentivity of MIDI (23 Jy,
 a difficult source for flux calibration but NOT correlated flux sensitivity).
The source is only barely resolved at 8-10 micron and should be observed with baselines
 at least longer than 60m until 90m.

The visual magnitude of the nova has stabilized to 11.7 and the dust formation has
 probably ended.

This means that the N band flux of the source will begin to slowly decrease.
Since we are already close to the sensitivity limit, these observations have to
 be performed as soon as possible.

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 ?

```
N/A
```

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 ?

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 ?
