This has been revised based on the results of Visit 12. We have established that of the two possible pointing options (Visits 20-27 and 30-37), the latter set produces much better results. Visits 20-27 have not been deleted from the plan but the ON HOLD comments indicate they should be withdrawn. Our remaining three visits should be scheduled from among the options given by Visits 30-37. In this resubmission, I also slightly reduced the exposure times in Visits 30-37 to avoid any possibility of saturation. -227577361 ----- Attempting Submission 3 (Tue Nov 05 18:58:58 GMT 2013) ----- ----- Attempting Submission 4 (Thu Nov 07 06:06:37 GMT 2013) ----- ----- Attempting Submission 5 (Tue Dec 10 18:05:23 GMT 2013) ----- Visits 20-27 are withdrawn. Visits 30-37 are on hold. Please schedule our remaining three visits from among the options given by Visits 30-37. Reading the Record of Cometary Impacts into Jupiter's Rings Images from the Galileo spacecraft were recently re-interpreted to reveal a subtle pattern of vertical "ripples" in the Jovian ring. These were shown to have been triggered during in mid-1994, and were probably associated with the impact of SL9 into Jupiter (Showalter et al., 2011, Science 332, 711-713). Additional patterns imaged by Galileo and also New Horizons indicate that these are common features of the ring; four different spiral patterns have been detected in the two data sets. Because any given pattern winds tighter at a known rate, these patterns can be used to infer the approximate the date on which the impact occurred. In addition, the vertical amplitude of the pattern constrains the impactor's mass. In Cycle 21, the rings of Jupiter are open to Earth by a small angle of 1.6 degrees, making this an ideal opportunity to detect similar patterns using HST. We will be able to detect any pattern in the ring that has an amplitude of >~ 1 km and that was triggered within the last 8-10 years. This information will provide valuable new constraints on the population of small bodies in the outer solar system. We target the tip of the Jovian ring in the UVIS2-C512C subarray. The orientation is carefully constrained to put the rings as close as possible to horizontal across the chip; this prevents the vertical saturation bloom of nearby Jupiter from entering into the subarray, and also keeps the rings away from Jupiter's broad diagonal diffraction spikes. We have three single-orbit visits near opposition in early January 2014. These are timed to sample three different rotational longitudes of the Jovian ring (which rotates in 7.1 hours) to see if the ripple pattern shows the predicted phase shift. These visits will also have the finest resolution on the ring, and can be oriented with the ring exactly horizontal in the subarray. Each of these visits consists of ~ 20 exposures of ~ 70 seconds duration through the broad filter F350LP. Two dither steps will be applied so that we the ring shifts relative to hot pixels and bad columns, and also so that we can potentially improve our spatial resolution. Two additional single-orbit visits are planned starting roughly 2 months before opposition, to see if the wavelength of the ripple pattern decreases with time, and to test for the optimal pointing and exposure time to use during opposition. Due to constraints on the orientation, the rings will be tilted by 15-25 degrees off the horizontal during these visits. Because the C512C subarray is in the corner of UVIS2 and we can potentially target either tip of the ring, we have the choice about whether to position Jupiter inside or outside the full UVIS2 chip. One of these positions may be better than the other for rejecting Jupiter's scattered light. During our first visits, we will take exposures of both ring ansas, which will enable us to determine if one option is better than the other for our subsequent visits. All later visits are designated "on hold" until these questions can be resolved.

It can also be used, if necessary, as an alternative to Visit 10 if scheduling difficulties arise. The scheduling data was generated by CASM 21.2. CASM was run in Phase II mode.

We image both the east and the west ansa of the ring in both subarrays C512C and M512C. We also try two different POS TARGS for the case where Jupiter is off the CCD. We bracket the exposure time so that we get usable results even if saturation occurs. The ring ansa is shifted 125 pixels downward in west ansa pointings, and 125 pixels upward in east ansa pointings, because this positions Jupiter closer to where it will fall when we use a different ORIENT in January, and thereby does a potentially better job of showing us how much scattered light to expect. 1386622183000 297.0 (Tic-Visit :proposal-id 13414 :visit-id "12" :proposal-version -1 :trans-version "20130919" :date "10-Dec-2013 09:49:14.0" :trans-errors '(:WARNINGS 0 :ERRORS 0 :HEALTH-AND-SAFETY 0 :FATAL-ERRORS 0 :CONTINUABLE-FATALS 0) :number-of-orbits 1 :saa-model "29" :si-bright-earth-limb-angle 20.0 :data-volume 134800 :tdrss-contact-duration 0 :coron NIL ) (Tic-Obset :proposal-id 13414 :visit-id "12" :obset-id "12" :pcs-mode "FGS" ) (Tic-Obset :proposal-id 13414 :visit-id "12" :obset-id "A2" :pcs-mode "FGS" ) (Tic-Obset :proposal-id 13414 :visit-id "12" :obset-id "B2" :pcs-mode "FGS" ) (Tic-Obset :proposal-id 13414 :visit-id "12" :obset-id "C2" :pcs-mode "FGS" ) (Tic-Orbit :proposal-id 13414 :visit-id "12" :orbit-number 1 :pcs-time 333 :si-vis-utilization 2635 :al-overhead-at-end 0 :internal-dur-at-end 184 :dark-offset NIL :dark-utilization 0 :max-dark-utilization 1920 :low-sky "N" :pcs-visibility 3015 :pcs-gap 0 ) true 1 0 The scheduling data was generated by CASM 21.2.
