Observing Information
General
- Current impact time
predictions (1994 July 16) from Paul Chodas et al., JPL.
- A table of times
each impact will rotate into view from Earth.
- Best estimates of the
impact times for the "lost" SL9 fragments.
- Ephemerides and
orbital elements
(1994 July 11) from JPL.
- A table of offset
ephemerides for each fragment.
- Plots (18K) of
the Jupiter-facing
hemisphere of Earth have been created for each of the impact times by L.
Wasserman of Lowell Observatory.
- A list of the best locations to observe
each impact, based on the most current astrometry.
Optical Observations
- The positions of Jupiter's satellites at the times of each impact, in
both a condensed and a
full version. (using July
5 astrometry)
- A table of offset
positions of the Galilean satellites from Jupiter, provided by John Spencer of
Lowell Observatory.
- A table of offset
positions for each impact, from John Spencer.
- A PostScript figure of
impact times and Jovian satellite locations, with accompanying
text.
- A sketch of Jupiter to
help amateur observers familiarize themselves with the planet's features before
the impacts.
- A table of Jovian moon events for July.
- A table of transit time for Jovian features for the month of
July.
- A table of transit
times for the Great Red Spot and white ovals on Jupiter.
- Information on appulses of
stars by the comet, by David Dunham.
- A plot of the
estimated limb and sunlight arrival times for the plume and fireball by
Mark Boslough et al. at Sandia.
Radio Observations
- An introductory paper into Jupiter radio emissions and what effects the
impacts might have on it, in
plain text and
PostScript formats.
- Miscallaneous information
about amateur radio observations of Jupiter.
- Predicted Jupiter radio storms for the following months:
