PI: Dr. Harold A. Weaver The Johns Hopkins University Applied Y Physics Laboratory CoI: Dr. Michael F.

Combi University of Michigan N ------------------------------------------------------------------------------------ Abstract We propose a 10-orbit program to observe any newly discovered bright comet as a non-disruptive Target of Opportunity during cycle 22. For a comet whose water production rate meets our basic ToO selection criterion, Hubble observations can be used to measure abundances of three highly volatile species (CO, CO2, and S2), providing critical information on the origin and evolution of the comet's nucleus. If the comet additionally has geocentric and heliocentric radial velocities in a favorable range, our Hubble observations will measure atomic deuterium emission, from which we can derive the D/H ratio for comparison to the values measured in other comets and Earth's water. The D/H ratio in cometary water is a key indicator of the role played by comets in the delivery of volatiles to the terrestrial planets. This is a non-disruptive ToO program because we anticipate that execution of the proposed observations need not be scheduled until at least 1 month after the triggering event. We have already identified four potential targets (C/2013 V5 (Oukaimeden), C/2012 K1 (PanSTARRS), C/2013 A1 (Siding Spring), C/2014 E2 (Jacques)), but it is still too early to tell if any of these will meet our ToO selection criteria. ------------------------------------------------------------------------------------ Observations Description ------------------------ We request 3 orbits using STIS/G230L with the 0.2 slit to measure CO Cameron, CS, S2, and OH emissions at 13 A resolution. Although the CO Cameron bands should be detectable with SNR>6 in 1 orbit for our minimal comet and a nominal CO2 abundance (~5%), 3 orbits would permit a more robust detection (SNR>10). Furthermore, if the comet is bright enough, measurements of CO Cameron emission in multiple orbits will determine whether the CO2 abundance varies with time, as it did rather dramatically (by a factor of ~2) during the EPOXI flyby of 103P/Hartley. 13874( 4) - 14-Jan-2015 18:57:28 - [ 2] For the observations of D (assuming the comet satisfies the requirements discussed in the proposal), we will use STIS/E140H with the 0.2 x 6 arcsecslit. This slit was used successfully to detect D in C/NEAT and provides a five-fold improvement in sensitivity compared to the standard 0.2 x 0.2 arcsec slit. We request 3 orbits to obtain a secure D/H detection, even for our minimal comet. We request a 1 orbit observation using E140H offset by a large distance from the nucleus, so that we can measure the H Ly-alpha emission in a region of the coma where it is optically thin. From these data we can derive a highly reliable H production rate, which is needed for the D/H ratio. We can also compare QH2O derived from this offset measurement to the values derived from the other orbits using OH emission. COS/NUV ACQ/SEARCH and ACQ/IMAGE will be employed in each COS orbit to accurately place the nucleus in the aperture (PSA). Similarly, a STIS/CCD ACQ will be employed in each STIS orbit. We also plan to take at least a couple STIS/CCD F28x50LP full-frame images during the course of our program to provide context for our spectroscopic program (e.g., to provide information on jets and other coma asymmetries). All the above orbits should be grouped within a 1-3 day period, so the comet's observing circumstances won't change significantly during that time. As always, we'll work closely with the program's PC to optimize the observing plan for our scientific objectives. ------------------------------------------------------------------------------------ 13874( 4) - 14-Jan-2015 18:57:28 - [ 3] TARGET LIST Solar System Targets ------------------------------------------------------------------------------------------------------------------------------------ TARGET NUMBER: 1 TARGET NAME: COMET-LOVEJOY ------------------------------------------------------------------------------------------------------------------------------------ TARGET DESCRIPTION: COMET Comet-Lovejoy-2014Q2 ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 1 TARGET POSITION LEVEL 2 TYPE=COMET, Q=1.290354613349346, E=0.9977694972445712, I=80.30301629940526, O=94.97534212651479, W=12.39562582691785, T=30-JAN-2015:01:41:08, TTimeScale=TDB, EQUINOX=J2000, EPOCH=20-NOV-2014, EpochTimeScale=TDB ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 3 WINDOWS ------------------------------------------------------------------------------------------------------------------------------------ DATA COMMENTS V = 15 +/- 3 Updated on 1/14/2015 to use Comet C/2014 Q2 (Lovejoy) as the target.
