General Description
Mid-infrared thermal imaging and spectroscopy of Jupiter to support the
New Horizons Encounter
The purpose of the observations is to study some spots located either on the southern
Jovian hemisphere (Great Red Spot (GRS), Red Spot junior (BA), South Polar Hot Spot
(SPHS)) or on the northern Jovian hemisphere (North Polar Hot Spot (NPHS)).
In imaging mode, Jupiter should be covered in 6 filters (see the OBs). It is important
that the reference star adopts the same chop/nod parameters as Jupiter. Note that
the chop-nod parameters have been tested succesfully in a previous Run. Since Jupiter's
diameter (about 44 arcsec) is larger than the imager's field, we ask for the centering
of the frame either on the southern hemisphere (decreasing declination) or on the
northern hemisphere (increasing declination). In particular, we wish in both cases
(northern or southern hemisphere) to centre Jupiter's central meridian on the frame
and to have its pole at the edge of the field (IMPORTANT: CHECK THAT THE POLE IS
WITHIN THE FIELD!!!).
In spectroscopy medium resolution mode, we select only one wavelength (8.6 microns).
The slit must be oriented parallel to the SOUTH-NORTH direction and should be centered
ON THE SOUTH POLE OF JUPITER.
The observing program is as follows:
- Feb 27: south pole spectroscopy (07:20-07:40 UT; OB MOV_Jup27a)
southern hemisphere imaging (07:40-08:20; OB MOV_Jup27b)
calibrations on Sig Lib (08:20-09:20; OBs: Sig_Lib_spec and Sig_Lib_img)
- Feb 28: northern hemisphere imaging (07:00-07:40 UT; OB MOV_Jup28a)
southern hemisphere imaging (07:40-08:20; OB MOV_Jup28b)
calibration on Sig Lib (08:20-09:00; OB Sig_Lib_img)
- Mar 01: southern hemisphere imaging (07:00-07:40; OB MOV_Jup01a)
northern hemisphere imaging (07:40-08:20; OB MOV_Jup01b)
calibration on Sig Lib (08:20-09:00; OB Sig_Lib_img)
Waiver Requests
Critical Observing Condition Constraints
Time-Critical Aspects
The periods of observations are imposed by:
- the motion of the Jovian atmosphere: the spots that we want to observed are visible
at the hours we have requested
- parallel observations with New Horizons, HST, Chandra and XMM

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 the provided finding chart is at a different wavelength than the observations,
did you clearly describe in the README file how to identify the target?
Did you specify a guide star brighter than V=12mag within a field of
r=5arcmin around the science target?
