Abstract

The rings of Uranus turn edge-on to Earth in May and August 2007. In between, we
will have a rare opportunity to see the unlit face of the rings. With the nine
optically thick rings essentialy invisible, we will observe features and phenomena
that are normally lost in their glare. We will use this opportunity to search
thoroughly for the embedded "shepherd" moons long believed to confine the edges of
the rings, setting a mass limit roughly 10 times smaller than that of the smallest
shepherd currently known, Cordelia. We will measure the vertical thicknesses of the
rings and study the faint dust belts only known to exist from a single Voyager
image. We will also study the colors of the newly-discovered faint, outer rings;
recent evidence suggests that one ring is red and the other blue, implying that each
ring is dominated by a different set of physical processes. We will employ near-
edge-on photometry from 2006 and 2007 to derive the particle filling factor within
the rings, to observe how ring epsilon responds to the "traffic jam" as particles
pass through its narrowest point, and to test the latest models for preserving
eccentricities and apse alignment within the rings. Moreover, this data set will
allow us to continue monitoring the motions of the inner moons, which have been
found to show possibly chaotic orbital variations; by nearly doubling the time span
of the existing Hubble astrometry, the details of the variations will become much
clearer.

  Observations Description
  ------------------------

     We will center the PC on Uranus and orient the rings as close as possible to
     the x-axis. With this orientation, we can saturate the planet and still obtain
     good detections of the rings and moons, because saturated pixels bloom along
     the PC y-axis. Visits must be timed to exclude the brightest moons---Ariel,
     Umbriel, Titania and Oberon. Miranda moves too quickly to be completely
     excluded, but we avoid times when it overlaps the main ring system. Some visits
     are specifically timed so that Mab is visible, so that we can study its orbital
     libration. In spring 2007 we will observe the rings with the PC during the
     brief window when Earth is on the north side of the ring plane but the Sun is
     still shining on the south side; the main rings will be especially dark during
     this period, potentially making fainter rings and smaller moons detectable. We
     will carry out four visits of three orbits each. Each orbit will begin and end
     with long, F606W exposures for moon tracking. One or two exposures in the
     middle of each orbit will obtain ring color using F450W and F814W. We will also
     obtain a small number of unsaturated images of the planet. We will position
     Uranus at slightly different locations at each visit so that any optical flaws
     tied to the PC pixel grid do not always overlap the rings. Horizontal dither
     shifts of ~ 2.5 pixels between each of the three orbits will also be used to
     refine radial resolution on the rings. During August-September 2007 we will
     obtain photometry of the rings and moons approaching opposition, while the
     rings are open to Earth by only a fraction of a degree. Four single-orbit
     visits will sample phase angles of approximately 0.5, 0.2, 0.1 and 0.05
     degrees. Filters F450W, F606W and F814W will be used to obtain color
     information. These visits will employ a 2.5-pixel dither shift along the x-axis
     to improve radial resolution on the rings.

Pattern_Comments:    This is a single horizontal shift along the PC pixel grid of 2.5 pixels. It
                     should enable finer radial resolution along the ring ansa, which is also
                     aligned (reasonably closely) with the pixel grid.

     Additional Comments: Extended search to study rings and moons, including Mab, with ring opening
                          angle <= 0.3 degrees. Uranus positioned 2'' above and left of the PC center
                          point, with 2.5-pixel dither shifts along the x-axis between each orbit.
                          Ring plane oriented <= 17 degrees clockwise from the x-axis, which is as
                          close to the x-axis as ORIENT constraints allow. Note that this visit has
                          limited scheduling opportunities according to APT. Visit 7C (marked ON
                          HOLD), relaxes the OLG constraints on Mab and can be used as an alternative
                          if this visit cannot be scheduled.

Visit: 7C
     Visit Priority:      <none>
     Visit Requirements:  SCHED 100%; ORIENT 210.0D TO 227.0 D; BETWEEN 05-AUG-2007:00:00:00 AND 13-
                          AUG-2007:00:00:00; ON HOLD
     On Hold Comments:    To execute only if Visit 73 cannot be scheduled.
     Additional Comments: Extended search to study rings and moons, with ring opening angle <= 0.3
                          degrees. Uranus positioned 2'' above and left of the PC center point, with
                          2.5-pixel dither shifts along the x-axis between each orbit. Ring plane
                          oriented <= 17 degrees clockwise from the x-axis, which is as close to the
                          x-axis as ORIENT constraints allow. This visit is ON HOLD as an alternative
                          to Visit 73. It should be more schedulable because it has no OLG constraints
                          on Mab. Please use in the event that Visit 73 is found to be unschedulable.

     Additional Comments: Edge-on ring photometry with phase angle ~ 0.7 degrees and ring opening
                          angle ~ 0.4 degrees. Mab near maximum elongation. Uranus initially
                          positioned 2'' below and left of PC center point. Ring plane oriented 11
                          degrees clockwise from the x-axis, which is as close to the x-axis as ORIENT
                          constraints allow. Dither shift by 2.5 pixels along x-axis for improved
                          radial resolution on rings.

                          parameter as close as possible to 210 degrees. This visit is timed to
                          include Mab but has limited scheduling opportunities according to APT.

     Additional Comments: Edge-on ring photometry with phase ~ 0.2 degrees and ring opening angle ~
                          0.7 degrees. Mab near maximum elongation. Uranus initially positioned 2''

                          for improved radial resolution on rings. Ring plane oriented <= 20 degrees
                          clockwise from the x-axis; please set ORIENT parameter as close as possible
                          to 210 degrees. This visit is timed to include Mab but has limited
                          scheduling opportunities according to APT. Should this visit turn out to be
                          unschedulable, use Visit 8C (marked ON HOLD) instead.

     Additional Comments: Edge-on ring photometry near opposition, with phase angle ~ 0.05 degrees
                          and ring opening angle ~ 0.9 degrees. Uranus initially positioned 2'' below
                          and right of PC center point. Dither shift by 2.5 pixels along x-axis for
                          improved radial resolution on rings. Ring plane oriented within a few
                          degrees of the PC x-axis. Note that this observation is only schedulable
                          during a 6.5-hour period on 9-Sep, according to APT. Nevertheless, this is
                          an extremely high-priority observation because it provides the smallest
                          possible phase angle and an optimized orientation. If this visit turns out
                          that this visit is unschedulable, then Visits 8D, 8E and 8F (all marked ON
                          HOLD) are offered as alternatives.

     On Hold Comments:    To execute only if Visit 83 cannot be scheduled.
     Additional Comments: Edge-on ring photometry with phase ~ 0.2 degrees and ring opening angle ~
                          0.7 degrees. Uranus initially positioned 2'' above and left of PC center
                          point. Dither shift by 2.5 pixels along x-axis for improved radial
                          resolution on rings. Ring plane oriented <= 20 degrees clockwise from the x-
                          axis; please set ORIENT parameter as close as possible to 210 degrees. This
                          visit is ON HOLD as an alternative to Visit 83. It should be more
                          schedulable because it has no OLG constraints on Mab. Please use in the
                          event that Visit 83 is found to be unschedulable.

     On Hold Comments:    First-choice alternative to Visit 84 if that visit cannot be scheduled.
     Additional Comments: Edge-on ring photometry near opposition, with phase angle ~ 0.1 degrees and
                          ring opening angle ~ 0.9 degrees. Uranus initially positioned 2'' below and
                          right of PC center point. Dither shift by 2.5 pixels along x-axis for
                          improved radial resolution on rings. Ring plane oriented <= 28 degrees of
                          the PC x-axis; please set ORIENT parameter as close as possible to 210
                          degrees. This visit is marked ON HOLD and is offered as the primary
                          alternative to Visit 84. It is much less desirable because of the higher
                          phase angle and because the orientation is less optimal. Nevertheless, this
                          observation is only schedulable during a few limited windows according to
                          APT. If it turns out that neither Visits 84 or 8D are schedulable, then
                          Visits 8E or 8F (both also marked ON HOLD) can be used instead.

     On Hold Comments:    Second-choice alternative to opposition Visits 84 and 8D if neither can be
                          scheduled.
     Additional Comments: Post-opposition visit for additional photometry and time coverage for Mab's
                          orbit. Uranus initially positioned 2'' below and right of PC center point.
                          Dither shift by 2.5 pixels along x-axis for improved radial resolution on
                          rings. Ring plane oriented within ~ 6 degrees of the PC x-axis. ON HOLD as
                          an alternative to Visits 84 and 8D if neither visit can be scheduled. Note
                          that this visit still has limited schedulability due to the requirement that
                          the rings be oriented very close to the PC x-axis. If this visit cannot be
                          scheduled, then Visit 8F (also marked ON HOLD), with a relaxed ORIENT
                          constraint, can be scheduled instead.

Visit: 8F
     Visit Priority:      <none>
     Visit Requirements:  SCHED 100%; ORIENT 30.0D TO 45.0 D; BETWEEN 30-SEP-2007:00:00:00 AND 15-
                          OCT-2007:00:00:00; ON HOLD
     On Hold Comments:    To execute only if none of Visits 84, 8D and 8E cannot be scheduled.
     Additional Comments: Post-opposition visit for additional photometry and time coverage of Mab's
                          orbit. Uranus initially positioned 2'' below and right of PC center point.
                          Dither shift by 2.5 pixels along x-axis for improved radial resolution on
                          rings. Ring plane oriented within ~ 15 degrees of the PC x-axis; please set
                          ORIENT parameter as close as possible to 30 degrees. ON HOLD as an
                          alternative to Visits 84, 8D and 8E if none of them can be scheduled. ORIENT
                          constraints are relaxes so visit should be more schedulable.
