Estimated Total Execution Time (hours, including overheads)

1.1 hours (approved), 1:05:55 hours (executed)

General Description

Imaging in B & V of a supergroup at z=0.37.  Target coords are
(11:19:53.7, -12:02:50.0).  Both B & V imaging require 1" seeing 
or better.  Dark-time is required.

A guidestar has been chosen to minimize vignetting of the field.
Its coords are (11:19:06.938, -12:07:04.94) with PPOS=POS.

To improve the chances of this OB being executed, we have relaxed
the airmass constraint to 2.5.

Waiver Requests

On advice of Martino Romaniello, we have relaxed the
airmass constraint to improve the chances of executing this
OB.  This is possible since it is only for imaging.

Subject: Phase 2 Waiver Request 076.B-0362B.01 Approved

Dear Dr Tran,

              your waiver for an OB of 1h06m can certainly be
granted! (our system is a bit rigid a times, sorry for that!)

Best regards,

Martino Romaniello

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 ?

```
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 specify suitable guide stars for all your OBs using Guidecam ?

Did you check that the chosen guide stars are suitable for all the offset positions and that they do not produce unacceptable vignetting of the field of view ?
