General Description

This is the set of observing templates for the VISIR observations of the
 dusty nova V1280 Sco.

Given our knowledge, the target is probably brighter than 5Jy in all filters. In
 that case, we prefer that the observations to be performed in BURST mode (alternative
 283.D-5020(D)), if possible. If not, the following templates should be used.

The calibrator, HD152834, is a M5 star, with a Iras 12micron flux of 8.2Jy. This
 flux is similar to the expected flux of V1280 Sco, and above the 5Jy threshold to
 allow burst mode observations. Therefore, the same calibrator has been chose for
 the VISIR templates A and D.

The VISIR observations are challenging: the source is a 0.3" diameter dusty ring.
 Therefore the best spatial resolution is needed to study it (implying good quality
 observations, and good PSF data too).

Last note: we are currently not able to check in the alternative templates, 283.D-5020(D),
 as they are not offered in service mode. Is a waiver request necessary?

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?

```
N/A
```

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 ?

```
N/A
```

If the provided finding chart is at a different wavelength than the observations, did you clearly describe in the README file how to identify the target?

Did you specify a guide star brighter than V=12mag within a field of r=5arcmin around the science target?
