abstract:
LINE_1: Comet Shoemaker-Levy (1993e) is a comet that has recently broken
LINE_2: up into many fragments, apparently somewhere in the vicinity
LINE_3: of Jupiter. Ground-based observations reveal a string of sub-nuclei
LINE_4: spaced over a distance of about one arcminute. HST observations
LINE_5: of this object with the WFPC-2 should reveal a fascinating spatial
LINE_6: morphology that is more detailed than any images obtained from
LINE_7: ground-based telescopes. Most importantly, WFPC-2 images of 1993e
LINE_8: should allow us to refine the nuclear size estimates that were
LINE_9: originally estimated from WFPC-1 HST observations in July 1993.
LINE_10: This proposal is for the July 1994 observations.

GENERAL_FORM_TEXT:
 QUESTION:3
  SECTION: 1
line_1: The program consists of ten separate visits to the comet with
line_2: all but one being devoted to imaging with the WFPC-2. One visit
line_3: is devoted to FOS spectroscopy near fragment 15 (G).
line_4: For the observations during the impact week, we have used
line_5: AT special requirements with UTC times for the orbits that
line_6: we hope to use. These latter choices were made AFTER consultation
line_7: with the latest version of the timeline for the 199 sms. These
line_8: ATs can be RELAXED by one or two orbits if necessary. Please
line_9: consult with me before making any larger changes.
 QUESTION:3
  SECTION: 2
 QUESTION: 4
  SECTION: 1
line_1: HST observations of Comet Shoemaker-Levy (1993e) should provide
line_2: better detail on the break-up of this object than is available
line_3: from any other source.

 QUESTION:  9
  SECTION:  2
line_1:ID no. 3064: Two sets of WFC images of comet Levy were obtained 6.5
line_2:hours apart on 27 September 1990 in order to investigate its temporal
line_3:variability. An arc of large grains was observed propagating
line_4:sunward with a projected velocity of 0.16 km/sec.
line_5:
line_6:ID no. 2481: P/Hartley 2 was successfully observed in late 9/91
line_7:These observations produced the first detection of CO Cameron bands in
line_8:comets. This emission is essentially a unique tracer of the CO2
line_9:abundance in comets. Additionally we obtained a beautiful spectrum
line_10:of the comet covering the entire spectral range 1200-6800 A, from
line_11:which we are compiling (still in progress) an inventory of volatiles
line_12:in that comet.
line_13:
line_14:ID no. 2483: Comet Shoemaker-Levy (1991a1) was successfully observed
line_15:in July 1992. Unfortunately, the comet was not as bright as we had
line_16:hoped, but we obtained data of comparable (slightly higher) quality
line_17:to that already in hand from P/Hartley 2. We definitely detected
line_18:the CO Cameron bands again, but it is much too early to say anything
line_19:more at this time.
line_20:
line_21:ID no. 2442: Comet Shoemaker-Levy (1991a1) was successfully observed
line_22:in July 1992, but it is too early to say anything more at this time.

line_2:Space Telescope, H. A. Weaver, M. F. A'Hearn, P. D. Feldman,

line_7:and P. D. Feldman, in "Science with the Hubble Space Telescope",
line_8:ESA-NASA CP, in press.
line_9:
line_10:Presentations on both the above programs have been made at several
line_11:scientific meetings, including the annual DPS meetings in 1990
line_12:(for 3064), 1991 (for 2481), and 1992 (2481 and 2483). A paper
line_13:on our detection of CO Cameron band emission in P/Hartley 2
line_14:will be submitted to a refereed journal shortly.
 QUESTION:   10
  SECTION:    1
line_1:The STScI has excellent data-analysis capabilities and also maintains
line_2:a pool of Science Data Analysts (SDAs) that are available to its staff.
line_3:However, SDA support for our program can only be assured if we are
line_4:allocated money to cover the SDA's salary.
line_5:
line_6:The other institutions co-sponsoring this program also have excellent
line_7:data analysis facilities and access to graduate students and research
line_8:assistants.  However, funds must be provided by this program in order
line_9:for the Co-Is to utilize these resources.
