That video isn't in daylight. That was the January 31 launch which launched at 6:11pm, about 10 minutes after sunset, I watched it from my backyard and it was fantastic (although the best view still goes to the Inspiration4 launch). Space/rockets interests me just as much as weather and I watch every single rocket launch from here in South Florida. After numerous tries of trying to see daylight launches in cloudless skies, I eventually gave up as they are simply not visible from here. And since the Astra rocket is 1/4 the size of a Falcon 9 and today's launch being at 1:40pm, there was a 0% chance of seeing it from Miami with the naked eye.
