Abstract: | We have used the ESO Schmidt telescope during the apparitions 1996, 1997 and 1998 to study the preceding Lagrangian cloud of Jupiter, L4. In our observed field of view, about 700 square degrees, during 1996 we found 399 moving objects that we classified as Trojans. From this we conclude that down to absolute magnitude H ≤ 13.0 there are ≈ 1100 Trojans in the L4 cloud. Proper elements of 696 numbered and multiopposition Trojans were calculated and one of these in the L5 cloud were found to be a non Trojan. A discussion of the Trojan proper elements is also presented. |
