Active Atmospheres on Uranus and Neptune
We propose Snapshot observations of Uranus and
Neptune to monitor changes in their atmospheres on time scales of
weeks, months, and years. Uranus is rapidly approaching equinox in
2007, with another 4 degrees of latitude becoming visible every year.
Recent HST observations during this epoch (including 6818: Hammel,
Lockwood, and Rages; 8680: Hammel, Rages, Lockwood, and Marley;
8634: Rages, Hammel, Lockwood, Marley, and McKay; and
10170: Rages, Hammel, Lockwood, and Marley) have revealed strongly
wavelength-dependent latitudinal structure and the presence of
numerous visible-wavelength cloud features in the northern
hemisphere. Long-term ground-based observations (Lockwood and
Thompson 1999) show seasonal brightness changes whose origins are not
well understood. Recent near-IR images of Neptune obtained using
adaptive optics on the Keck Telesccope together with images from our
Cycle 9 Snapshot program (8634) show a general increase in activity
at south temperate latitudes as well as the possible development of
another Great Dark Spot. Further Snapshot observations of these two
dynamic planets will elucidate the nature of long-term changes in
their zonal atmospheric bands and clarify the processes of formation,
evolution, and dissipation of discrete albedo features.
These are Snapshot observations of Uranus and Neptune to monitor changes in their zonal bands and discrete albedo features on time scales of weeks and months, in order to characterize the underlying changes in the vertical cloud and aerosol structure. In contrast with standard GO programs, which in the past have produced observations separated by intervals of a year or more, we intend to obtain data at intervals of 1-2 months. In exchange we sacrifice longitudinal coverage and limit the use of filters with long exposure requirements.
Our filter selection is designed to constrain the vertical aerosol distribution responsible for the latitudinal bands and albedo features seen on Uranus and Neptune. We match the filter choices with those used for past HST observations, and with past groundbased observations (for continuity). The filters sample a wide range of methane absorption coefficients, which translates into probes of a wide range of depths in the atmosphere. (This is the primary reason for including WFPC2, since ACS lacks the 619-nm methane band filter, in particular, which is critical for unambiguous determination of the vertical distribution of clouds and aerosols in the tropospheres of Uranus and Neptune.) The F467M (WFPC2) and F475W (ACS) filters cover an optimum wavelength range for the detection of Great Dark Spots.
Since all six WFPC2 filters will not fit into a single 30-minute SNAPSHOT observing period, we split visits to Uranus into two separate groups--a blue filter group and a (mostly) red filter group. We limit the use of short-wavelength WFPC2 filters for Neptune, to concentrate on fairly long exposures in the 619-nm methane filter. ACS/HRC visits are also split into two groups so that some visits can include the F892N methane-band filter. (Although no F892N images of Neptune were requested in the proposal due to doubts about their feasability within a SNAPSHOT observing window, recent ACS observations of the planet under Cycle 13 GO program 10423 (PI Heidi Hammel) have shown that reasonable DN values can be obtained with exposure times of ~200 s.)
We are requesting 6 WFPC2 visits and 12 ACS visits to both Uranus and Neptune, spaced at intervals of 1-2 months throughout the portion of Cycle 14 outside each planet's solar exclusion window--36 visits in all.
