The ISS passes are exceptionally bright at the moment too - very clear last night, looks similar for today, 21.14pm from West to East (ish).

Just a heads up that the SpaceX launch (Falcon 9 with 57 satellites) is planned for tomorrow at 16.54pm BST. Info n Satellite visibility post-launch will follow on the site below but obviously will be too light to see the Falcon go over after take-off...
When do you think ? Will be too light to spot it after launch (usually about 15 mins before it goes over us - was looking for SL 5 last night but even at 10.15pm it was too light, particularly as the path was slightly to the North of us).....guessing c90 mins after on second pass maybe ?
