General Description
Mid-infrared imaging and spectroscopy of Jupiter to measure the temperature,
cloud and minor constituent fields around around its two giant anticyclonic vortices,
the Great Red Spot and the ?Little Red Spot? in several epochs around their closest
approach in July 2008. These two spots are located on the southern hemisphere.
Spectral observation blocks (MR 7.5-9.3 microns) have been generated for non-specified
targets (likely to be Jovian vortices), which will be specified closer to the dates
of the observations. Imaging observation blocks containing seven filters have been
created to cover the south hemispheres.
In order to get images of both spots at the same time, we will update the time constraints
before the observing period. Indeed, the drift rates of Oval BA and GRS will be
checked after the solar conjunction with Jupiter (these rates are actually poorly
constrained).

Time-Critical Aspects
In the table below, dates in which the region of interest are unavailable
are
not included (we are close to Jupiter's opposition, so there aren't many!) With
Jupiter south of the equator, the VLT is in an ideal position to observe
Jupiter.

Special Execution Requirements
The total integration time on each filter is 60 seconds. Each sequence
must be repeated two times at each epoch with an offset of few pixels to correct
for bad pixels. Do not run the acquisition again, just offset the telescope by 3
pix in RA and 3 pix in DEC, ask the night assistent to do so.
The weather flag must be set to P because Jupiter is bright and would otherwise
produce striping.
Pointing: The LRS and GRS are available on the same night. Second chop position
will be discarded, so ensure chop throw is sufficient to minimize overlap on the
planet.
POINTING: For the southern hemisphere imaging, Jupiter should be centered right-left,
with the southern limb some 3-4 pixels above the bottom of the field of view.
Special Calibration Information
Imaging of standard stars in all filters.
Observations of bright standard stars for spectral calibration.
Multiple calibration blocks have been created in case observations aren't conducted
concurrently, but these may not all be necessary. One spectral calibration per
wavelength and one image per wavelength is all that is required if all observations
are conducted on the same night.
