After this evening's scrub, the next launch opportunity for the SpaceX DRAGON

Here is an updated TLE for the first revolution, assuming launch on June 3,
21:07:00 UT:

DRAGON CRS-11						
1 72001U 17009A   17154.89769380 0.00000000  00000-0  00000+0 0    07
2 72001  51.6320 104.7434 0115859  44.2809  71.5413 15.98180622    01

It is based on the initial TLE of CRS-10.

Sighting conditions for west Europe, 20 minutes after launch, increase, in the
sense that it will enter earth shadow more eastwards than it would have done at
the original launch time, which for NW Europe means a longer visible sky
trajectory. For my location in the Netherlands, this is late twilight (sun at
-10 deg altitude)

The moonphase however has grown and is more of a nuisance.

Shadow entry would be near 21:31:00 UT.
