	Giotto will have its closest approach at 9:59.50 GMT 2 July 1990.

	Closest aproach to Earth surface will be in the Indian Ocean close
to the Southern tip of Austrailia at a distance of 22680 km.

	Giotto will just be visible to the Amature (if they are in OZ else
forget it)

	Magnitude : Most Probable 10-12 th
		  : Optimistic 8 th

	Professional Observers should have details of orbital elements &
ground track. The main difficulty will be in working out the star coords.

	If still intrested (and BT willing) I will have the Hyperbolic
Orbital Elements by Friday. Mail me >>>>
