SpaceX Dragon - Spacecraft visible from Europe T+23 min
For Europanons – if the Dragon launches, you can see it pass over Europe about 23 minutes after launch (will be in evening twilight skies for you, space capsule in sunlight, so will shine like a brightly moving star). Also alongside will be the rocket's upper stage, so two objects, may be close together. This link from an astronomer in the Netherlands includes sky charts showing how high the Dragon will be in the sky from various major cities across Europe.

Near Kennedy Space Center: NOAA has issued a tornado warning in the Haulover Canal area. Weather … seems problematic today. Still counting towards launch, as far as I can tell. Florida weather is dynamic, sometimes it looks really bad and then clears up, but this does not feel ideal. Could easily fly today, seems about 50-50.
