C/ISON is predicted to be very bright this fall (naked eye visibility), with large gas production rates enabling higher than usual sensitivities to be achieved. We propose a series of HST observations of C/ISON that aim to: (1) monitor the evolution of CO production with heliocentric distance, (2) search for compositional changes associated with the intense heating episode during the comet's close approach to the Sun, and (3) measure D/H in this comet. Our focus here is on scientific objectives that are uniquely accomplished via ultraviolet observations with Hubble. ------------------------------------------------------------------------------------ Observations Description ------------------------ We plan to observe C/ISON at 3 different epochs, comprised of the following: (1) On 2013-Oct-7, or slightly afterwards: 3 orbits total with 2 orbits of COS/FUV for CO 4PG and 1 orbit for STIS/G230L for OH and CS. This will provide measurements of the volatile abundances at r~1.54 AU, although CO Cameron and S2 are long shots at this time. These 3 orbits should be consecutive. (2) On 2013-Nov-4, or slightly before: 8 orbits total with 2 orbits of COS/FUV for CO 4PG, 2 orbits for STIS/G230L for OH and CO Cameron, and 4 orbits for STIS/E140H for D/H (3 for D and 1 for H well off the nucleus, where it is optically thin). This will provide measurements of the volatile abundances at r~0.92 AU, including pre-perihelion D/H. If possible, we want these 8 orbits to 13492( 11) - 16-Oct-2013 10:02:07 - [ 2] be consecutive. (3) On 2013-Dec-18, or slightly after: 8 orbits total with 2 orbits of COS/FUV for CO 4PG, 2 orbits for STIS/G230L for OH and CO Cameron, and 4 orbits for STIS/E140H for D/H. This will provide measurements of the volatile abundances and D/H ratio at r~0.78 AU, post-perihelion, after the massive heating event. We note that the shedding of substantial mass near perihelion might result in a very different volatile composition post-perihelion, if there is significant variation of the composition with depth in the nucleus. If possible, we want these 8 orbits to be consecutive. We have defined 3 different C/ISON targets for the three different epochs (one for each epoch) to reduce confusion because we expect to use different orbital elements for each epoch. However, in the initial submission the same orbital elements are used for all three epochs. These latter elements should be good enough for preliminary planning, but should be updated before the final GS selection and bright object checks are made. There is also an OFFSET target identified for epochs 2 & 3, which will be used for the STIS/E140H orbits when we're offsetting on the sunward side of the nucleus into a region where the H Ly-alpha line should be optically thin. We will use "requires ephemeris correction" commands to perform the final pointing adjustments, roughly 3 days prior to the execution of the observations. We use a different correction ID for each of the 3 epochs.
