Anglo-Australian Telescope Infra-red images from July 21. The image 
consists of three panels taken at 6:01pm (upper), 6:51:pm (middle) 
and 10:08pm (lower)(Aust Eastern Std time) with the IRIS Infra-red 
Imaging Spectrograph on the 3.9m Anglo-Australian Telescope at Siding 
Spring Observatory near Coonabarabran in north-west NSW. The observing 
team is led by Dr. David Crisp from the Jet Propulsion Laboratory in 
Pasadena. In the upper panel, impact sites from fragments H, Q1, Q2 and 
R, (the latter of which had hit Jupiter some three hours earlier), G and 
L are visible (left to right). The large disturbed regions from fragments 
G and L are particularly prominent. In the upper part of this picture, 
the Jovian moon Io is passing in front of the planet. In the middle panel, 
the impact regions visible are (again left to right) E+F, H, Q1, Q2+R, G 
and L. Jupiter's Great Red Spot can be seen on the extreme left at a 
latitude above the impact regions. The moon Io continues to pass in front 
of the planet. In the bottom panel, Jupiter has rotated so that the Red 
Spot is now on the extreme right of the image. Impact regions visible 
(left to right) are P2, C, A (from the first fragment which hit early 
Sunday morning AEST), E+F and H. The last fragment "W" will hit Jupiter at 
6pm on Friday evening and the AAT will once again be well placed to observe 
the impact. The impact sites will continue to be studied for some months to 
monitor the evolution of the impact sites.
