General Description

Simple polarimetric imaging of an exploding star.

Please always execute the STD OB together with the corresponding science OB.
Please feel free to adjust DIT & NDIT in order to have a good flux but without
having the central core leaving the linearity regime.

Since the target is presently fading, the AO configuration might not be optimal.
Even if the OB does not say anything, pls try to  use mode 3-2.

Normally the polarimetry should be executed under photometric conditions,
clear weather is requested here to increase the probability to have the object observed.

Stars of brightest magnitude:
11 for the object and 9 for the standard. (last available measurements)

Waiver Requests

No Waiver Request was submitted

Critical Observing Condition Constraints

Please make sure the central star does not exceed the linearity range.
Adjust DIT*NDIt if needed.
 (We are looking for the extension)

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?

```
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 you have PSF reference star OBs, do the names of those OBs begin with PSF_ ?

```
N/A
```

If there are Finding Charts attached to your OBs, is the field-of-view of at least one of these charts 2' x 2' (with clearly labelled field orientation) ?

Have you clearly marked and labelled your wavefront reference objects R1, R2, R3, ... (as specified in the NAOS Preparation Software) on your Finding Charts ?

Have you specified the magnitude of the brightest object in the field-of-view for each OB ?

Are there objects in any of your fields (including standard stars) which are brighter than the limits specified in the User Manual and on NACO web Pages ?

If the previous answer is yes, have you given a list of OBs and a justification for the brightness limit violation in the general description field ?

N/A
