- FIRST COMETARY IMPACT ONTO JUPITER OBSERVED AT CALAR ALTO OBSERVATORY
-
- A time sequence of four frames showing the impact of the first of the
- 20 odd fragments of Comet Shoemaker-Levy 9 into Jupiter. The upper
- left frame shows Jupiter just before impact. The bright object to the
- right is the closest Galilean satellite Io, and the fainter oval
- structure in the southern hemisphere is the Great Red Spot. The polar
- caps appear bright at the wavelength of the observations, 2.3 um,
- which was selected to maximize contrast between the fireball and the
- jovian atmosphere. In the second frame, taken from Spain at about
- 10:15pm on July 16, the fireball appears above the southeast (lower
- left) limb of the planet. The fireball flared to maximum brightness
- within a few minutes, at which time its flux surpassed that of Io.
- The final frame shows Jupiter approximately 20 minutes later when the
- impact zone had faded somewhat. Further monitoring suggests that the
- bright zone is rotating slower than the cloud deck on Jupiter,
- implying that the fireball is high in jovian atmosphere. At the time
- of this writing nearly three hours after the event, remnant flux is
- still visible. These images were taken at the German-Spanish 3.5
- meter telescope on Calar Alto in southern Spain, using the near
- infrared camera of the Max-Planck-Institut fuer Astronomie in
- Heidelberg, Germany.
