Estimated Total Execution Time (hours, including overheads)

5h, OB1: 19m55s; OB2-5:1h0m0s; OB6: 40m05

General Description

We aim at high S/N spectra of the B-type main sequence star HE0437-5439
 (B=16.2mag). Due to rotation the lines are somewhat broadened. Therefore non-optimum
 resolution is sufficent and a wide slit of 1.4" is acceptable. Therefore we can
 accept mediocre seeing conditions up 1.4". The total integration time is split in
 9 individual exposures to be executed in 
five OBs.  

In order to maximise S/N should be observed at low airmass (<=2.0) and good transparancy.

For proper rectification we want to observe a DC-White dwarf, WD1055-072 (B=14.33mag).
 We changed the DC with respect to the proposal for better accessibility. Note that
 the
star has a HIGH proper motion: p.m.(alpha)=-0.79"/yr; p.m.(delta)=0.08"/yr!

S/N has been estimated with the UVES ETC using a blackbody of the appropriate temperature,
 airmass=2.0, seeing=1.4", slit width=1.5", 7 days from New Moon.

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 ?
