I just spotted Station flying almost directly over Antwerp, Belgium at 12:32 UTC (so about 20 minutes ago) and didn't spot anything trailing for a solid 5 minutes.  "Spot the Station" claims the HTV was visible exactly 20 minutes later at a lower elevation.

Hm. Then I must have just missed it. But "lower elevation" has clouds here right now, already was pretty lucky about ISS

A1 job Pete.

Congrats to JAXA on a great launch.

I've got a 67 degree ISS pass at 1037 tonight. Has anyone had luck spotting the HTV?

Brilliant ISS -3 Magnitude pass but no joy on HTV--waited 13 minutes.  Did see USA-186 as predicted by HA flare nicely to Mag 0 or -1.
