3 weeks, roughly in line with faster Space Shuttle turn around times
The shortest shuttle turnaround time was 55 days. Almost three times as much as Falcon 9. The fastest post-Challenger turnaround time was 88 days, I believe. After Columbia, the fastest turnaround was around 5 months.
NASA claimed that the shuttle could achieve a turnaround time of two weeks (page IX). It looks like SpaceX is not the only one setting unrealistic timelines?
You can check heavens above (adjust your location) to check when it will be visible for you.
Wait a second, it’s going to pass over my house in 5 minutes!
Edit: Shit, clouds!
Edit2: I was able to see it through a few gaps in the cloud cover!
