A clear summernight. At dusk the moon, Mercury, Venus and Mars were
visible in the west; at dawn Jupiter rose in the east.
During the night the northern sky remains brigth at the horizon, due
to high clouds in the atmosphere illuminated by the sun.

I made the following obs during this night:

70- 25CD 99-06-18 23:16:20   LB   78.9 0.5   4 19.7   AA, mag 4->inv
70- 25CD 99-06-19 00:59:50   LB  119.8 0.2   6 19.96  FF, mag 5->inv
70-108 A 99-06-18 23:27:28   LB   56.9 0.5  10  5.69  AA, mag 6->8

87- 11 A 99-06-19 01:29      LB                       almost S, mag 5
Probably the last obs of 87- 11 A is of another sat because of
differance between the passing intervals.
