TRASP 4

Comets at TIRGO

Fragmets in the Hyakutake comets

These two images were obtained at TIRGO on March 25, 1996, in the J band. The bright spot on the upper left is the comet nucleus, while a fragment moving away from the nucleus is visible near the center of each image. Comparing the two images it is possible to see that the velocity of the fragment is 17 m/sec.

The impact of SL9 on Jupiter
These images have been obtained at TIRGO in July 1994 when the fragments of comet Shoemaker-Levy 9 (1993e) collided with Jupiter.
The planet and its satellities Io and Europa were imaged before (upper) and after (lower) the collisions, using a narrow-band filter at the wavelength of a deep methan absorption band (2.35 micron). At these wavelength only the polar caps of the planets can be seen. The results of the collisions are the spots near the southern polar cap of Jupiter.
