Estimated Total Execution Time (hours, including overheads)
General Description
After run A, we warmly thank ESO staff: we got incredible images ! Amazing
!!!
This is run B, and we propose to repeat similar observations.
This is taff job: observation of Jupiter using a satellite as AO reference. It is
challenging.
Io is bright, magV=5, so VIS WFS is to be used. No finding chart, IO size ~1.1 arcsec
Please center Jupiter (size=45\") into Conica.
Jupiter great red spot is the main target.
First, series of 6 NB filters are observed, with small jitter offset, but no sky.
After run A, DITxNDIT have been adjusted, there should be no saturation. For NB109,
we put a ND filter.
Later, AO loop is opened and apply a large offset (60arcsec RA + 60 Dec) to go to
sky, again a series of same NB filters for sky only (no AO).
Then this is done.
1 OB for science, 1 OB for standard star.
To make things easy, coordinates are correct if OB starts 29 August, 04h00 UTC (as
indicated into name). Please be right in time, because Io will run onto Jupiter
and eventually the OB becomes impossible to complete if late... Also, airmass is
getting huge.
In case night 29 August failed, a second science OB has been prepared, using Callisto
as AO reference: to be run ++only++ if night 29 August was not executed, starts
30 August, 01h20 UTC (as indicated into name). Since it cross zenith, you have to
start at 01h20 UTC since ALT=85deg.
Any problem, call me home: + 33 1 40 30 37 95, any time.
Thank you and good luck !!! Olivier Marco
Waiver Requests
A Waiver Request was submitted, no answer so far. We ask for a longer
OB:
For this special project, AO loop is locked on a (fast moving) satellite of Jupiter
(Io or Callisto), which is time critical.
This may take quite some time to successfully lock the AO system, and we have allocated
time for that task (we required a 2 hours SM allocation).
We would like to spend 1.5h for 1 science OB (including preset, setup, science with
several filters) and 0.5h for 1 OB night time standard star using NB filters. So
we request a weiver to allow to run a unique 1.5h OB in one shoot. We agree that
if conditions change OB will not be repeated.
Critical Observing Condition Constraints
Time-Critical Aspects
Since the AO system has to be locked on Io satellite, this can be done
only when it is located at a suitable distance.
We choose the date & time so that the distance Jupiter - Io is always less than
50\"
The coordinates of both Jupiter & Io in the OB are given for the time of the
preset, if it is done in time no modification is necessary.
Special Execution Requirements
Special Calibration Information
We need flux calibration for all the NB filters we use.
Please run the dedicated OB with an ESO photometric standard.
Star is: HD188112, B9V, J=10.708, H=10.787, K=10.860

Is this a Pre-imaging run ?
Pre-imaging Requirements
Source(s) of Pre-imaging
Pre-imaging sources not listed above
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 ?
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?
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 ?
If you have PSF reference star OBs, do the names of those OBs begin with
PSF_ ?
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 ?
