Critical Observing Condition Constraints
Time-Critical Aspects
These observation blocks should be conducted as early as possible in P81
to capture changes since Sept/Oct 2007. We have listed below a table of the dates
in May/June 2008 when either or both the Great Red Spot (GRS, expected longitude
~80 deg W) or the Little Red Spot (LRS, expected longitude ~130 deg W) are available.
We have eliminated times when Jupiter is greater than than 1.7 airmasses and the
local time is after 6:00 am (1000 UT).
For each date, we list below the times when each feature is expected to cross Jupiter's
central meridian (cm). The features can be obsered as much as 1.5 hours on either
side of this time without suffering significant foreshortening.
Optimal timing choice: Our highest priority imaging (SET 1) can be performed most
efficiently on dates/times when both southern-hemisphere features are available
on the disk, as noted. Observations of the southern hemisphere on the opposite side
of the planet (a lower priority, SET 2) would then be made near the same time on
the subsequent night, or even later at multiples of 10 hours with a 5-hour phase
offset. Alternatively, the GRS and LRS can be imaged individually (as SET 1 and
SET 2), as noted.
Spectroscopy can be performed on any night either feature is (or both are) available.
It is a lower priority than the multi-spectral imaging of both features.

Please execute the OBs in the following order:
SET ONE:
1. MOV_img_jup_south_set1 (6 filters, 60s exposures, repeated twice with a 3 pixel
offset = 38.5 mins).
2. CAL_img_star (6 filters, 60s exposures, repeated twice with a 3 pixel offset
= 38.5 mins).
SET TWO:
3. MOV_img_jup_south_set2 (6 filters, 60s exposures, repeated twice with a 3 pixel
offset = 43.5 mins).
GRS SPECTROSCOPY (Can be on any night feature is available):
4. MOV_spectr_jupiterGRS_HR8.02
5. CAL_spectr_star_HR8.02
6. MOV_spectr_jupiterGRS_MR7.5-9.3
7. CAL_spectr_star_MR7.5-9.3
LRS SPECTROSCOPY (Can be on any night feature is available):
8. MOV_spectr_jupiterLRS_HR8.02
9. CAL_spectr_star_HR8.02-0
10. MOV_spectr_jupiterLRS_MR7.5-9.3
11. CAL_spectr_star_MR7.5-9.3-0
SET 3: NORTHERN HEMISPHERE IMAGING (Any night Jupiter is available):
12. MOV_img_jup_north_set1_may08 (6 filters, 60s exposures, repeated twice with
a 3 pixel offset = 38.5 mins).
NB1: We request that the MOV_img (SET 1, SET 2 and SET 3) observations are taken
on the same night so that CAL_img can be used to deconvolve the PSF. If this is
not possible, we intend to use the calibrator stars offered by the observatory for
our calibration of MOV_img_jup_south_set2 and MOV_img_jup_north_set1_may08.
NB3: Blocks 1 and 2 must be executed together. Spectra and their calibrators must
be executed together.
NB4: In the observation blocks, RA and DEC have been given for April 1st 2008, modifications
can be found in the ephemeris datafile.
Special Execution Requirements
Within a single MOV_img block, the total integration time on each filter
is 60 seconds. Each filter must be repeated again 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 and repeat the observaton
IMAGING SEQUENCE: Our first priority is to survery the southern hemisphere, with
particular emphasis on the Little Red Spot (LRS) and the Great Red Spot (GRS), together
with imaging of a calibration star. This is a bit complicated, because the LRS
and GRS may actually be available on the same hemisphere on some nights (they are
60 deg apart in longitude and cross the planetary central meridian ~1-1/2 hours
apart: see the Timing Constraints section).
.
If only the GRS is observed, then the LRS should be observed next, and vice-versa.
If both are captured, then roughly the opposite hemisphere
should be observed. If time permits after spectroscopic OBs are executed, sample
the northern hemisphere at an artibtrary longitude. (This is priority 3, behind
the spectroscopic OBs.)
INTEGRATION TIME: With the Q-filters, integration times of 20s would be sufficient
to produce a good image. The key priority of this observing run is image quality.
10s of integration is sufficient for the calibration star imaging (shortening the
execution time dramatically). Reduced integration times should be used, if possible.
WEATHER FLAG: The weather flag must be set to P because Jupiter is bright and would
otherwise produce prominent horizontal striping.
POINTING: The second chop position will be discarded, so ensure chop throw is sufficient
to minimize overlap on the planet's southern hemisphere.
This can be set at 20 arcsec. For 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. For northern hemisphere imaging, the northern limb should be
3-4 pixels below the top of the FOV.
POINTING FOR SPECTROSCOPY: Rotate slit so that it lies north-south across the target
(see finding charts).
