The Analysis of the H Lyman α Emission Line Profile from Jupiter's Aurora
Ballester, Gilda E.; Prangé, Renée; Clarke, John T. +3 more
We present the analysis and modeling of the emission spectra of the jovian northern auroral region taken from May 28 to June 3, 1993, with the Goddard High Resolution Spectrograph on board the Hubble Space Telescope. They extend from 1204 to 1240 Â covering H Lyman α and part of the Werner and the Lyman bands of H 2. We used the 2×2 arc…
HST/FOC Imaging of Triton
Stern, S. A.; Stansberry, J.; Flynn, B. +1 more
We present an analysis of HST/FOC images of Triton obtained on 20-24 September 1995. Images were taken in two wavelength bands using the F278M and F410M filters in order to obtain the first mid-UV map of Triton and to place further compositional constraints on Triton's surface by imaging farther into the UV than did Voyager. Our disk-resolved imag…
AAT Observations of the SL9 Fragment C, D, G, K, N, R, V, and W Impacts with Jupiter: Lightcurves and Imaging
Crisp, David; Spencer, John; Orton, Glenn +2 more
We used the InfraRed Imaging Spectrometer (IRIS) on the Anglo-Australian Telescope to monitor the July 1994 impacts of Comet Shoemaker-Levy 9 with Jupiter. Spectral image cubes were obtained for the impacts of fragments C, D, G, K, R, and W. These data provide time sequences of spatially resolved spectra in K-band (1.98 to 2.40 µm), with a s…
Ground-Based Observations of the 10 August 1995 Saturn Ring-Plane Crossing
Nicholson, Philip D.; Matthews, Keith; McGregor, Peter J. +2 more
Observations at 2.3 µm at the Australian National University 2.3-m telescope at Siding Spring Observatory and the 5-m Hale telescope at Palomar Observatory from 9 to 17 August provide a longer baseline of time around the 10 August 1995 Saturn ring-plane crossing than space-based observations. The edge-on photometric thickness of the rings at…
