Estimated Total Execution Time (hours, including overheads)

```
00:59
```

General Description

This is a monitoring of a single star, suspected to be an almost critically
 rotating, yet magnetic star. 

Run C OBs should be executed in September

Goal is a) fill the phase diagram b) confirm period of 0.56 days and long term stability
 of period, and c) determine eventual secular changes in circumstellar material.
 No need to stick to a special timing, but the OBs should not be executed immediately
 one after the other in order to give the stellar spectrum some time to change. Minimum
 waiting time between two subsequent OBs is 3 hours.

Waiver Requests

```
No Waiver Request was submitted

Critical Observing Condition Constraints

None. 
In case executed under conditions worse than specified: This is ok as long as the
 goal S/N of 200 or more is reached.
In case executed under better conditions: Make sure the spectra are still in the
 ,inearity range.

Time-Critical Aspects

This is a monitoring, although not with strict timing requirements. However,
 at least 3 hours should pass between two subsequent OB executions.

Do all your OBs comply with the instrument-specific requirements listed on the instrument-specific Phase 2 web page ?

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 specified the S/N ratio at given wavelength in the User Comments field of each OB?

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
