Abstract We propose to image Uranus as the planet plunges toward equinox in 2007. Recent HST images during this unique epoch (6818: Hammel, Lockwood, and Rages; 7429: Tomasko and Karkoschka; 7885: Hammel, Karkoschka, and Marley) have revealed: (i) strongly wavelength-dependent latitudinal structure, (ii) the presence of numerous visible- wavelength cloud features in the northern hemisphere, (iii) zonal winds which may deviate from the smooth profile implied by the Voyager observations in 1986, and, (iv) in the near-IR, discrete features northward of +25 degs that have the highest contrast ever seen for a Uranian cloud (Karkoschka 1998, Science 393, 765-767; Hammel et al 2001, submitted to Icarus). Specific scientific issues we will address with new observations are: whether the northern features are indicative of intrinsic change or result simply from a change of viewing angle; the shape and stability of the zonal wind profile; and the source of the as-yet unexplained variations of the atmospheric reflectivity. When possible, observations will be coordinated with ground-based imaging, spectroscopy, and photometry. This period approaching equinox is the first opportunity (in the era of modern instrumentation) to examine the far regions of the northern hemisphere on Uranus. ------------------------------------------------------------------------------------ 9235( 3) - 05/22/01 11:29 - [ 2] Observations Description ------------------------ To fully map Uranus in longitude, four "samples" are required, separated in time by about 2 orbits (i.e., every third orbit). This spacing (every 288 minutes) will yield images at about roughly a quarter of the planet's atmospheric rotation period (about 18 hours on average = 1080 minutes). To have adequate baseline for the zonal wind measurements, two measurements of the same longitude are required separated by at least one (or preferably more than one) rotation. We cannot predict the longitudes of discrete features. Thus our total request is for two maps, i.e., 8 orbits. An orbital longitude constraint is applied to try to obtain Uranus observations near opposition on 16 August (NOT between 60 and 340). Uranus subtends more than 3.7 arcseconds then (compared to less than 3.5 arcsecs before May or after mid-November). This constraint can be relaxed if scheduling is difficult. We hope to coordinate the HST observations with ground-based observing at several sites. We may propose for infrared spectroscopy at the NASA IRTF in August 2001 with the SpeX infrared spectrograph and we will also be obtaining photometry at Lowell Observatory in this time period. If the HST images can be scheduled to be close to opposition, this would greatly enhance the scientific return from all observations by creating a robust complementary data set (HST visible imaging, IR spectroscopy, and visible photometry which is directly tied to the long-term record).
