The 45th Weather Squadron of Space Launch Delta 45 has released their L-1 Launch Mission Execution Forecast: 60% GO improving to 20% GO through the launch window.

Online Viewing

SpaceX will have a livestream of the launch on their website: Starlink 12-13.  This will also be available on the X platform. Coverage starts about fifteen minutes before liftoff.

Spaceflight Now will have coverage of the launch starting about one hour before liftoff on Youtube: link

For official updates regarding launch times, SpaceX.com is the best source of information. Starlink launch times change from time to time, and the company generally updates their website within minutes of the decision to change the launch time. This is very handy if none of the streaming options on YouTube have started their broadcasts.

Remember that there is a delay between a launch stream and the actual countdown clock. That is simply because of physics: it takes time for the signal to travel from the launch site, through the Internet, and back down to your phone, resulting in a five to fifteen-second delay.
