Hey, space fans! SpaceX is counting down to launch its Dragon spacecraft in the wee hours of Saturday, Jan. 10, and the predawn Falcon 9 rocket liftoff just might be visible to early-bird skywatchers long the U.S. East Coast, weather and local conditions permitting. I've had the luck to see a SpaceX night launch in person, as well as watch from northern New Jersey as rockets launched from Virginia arced across the sky, so I can tell you it's an amazing sigtht to behold, if you can see it.

Here's an afternoon reminder on where to look early Saturday in case you live in a region where you might be able to see the launch: SpaceX plans to launch the Falcon 9/Dragon mission at 4:47 a.m. EST (0947 GMT) from its pad at the Cape Canaveral Air Force Station in Florida. You can watch the SpaceX launch live online starting at 3:30 a.m. EST (0830 GMT), courtesy of NASA TV. And as our skywatching columnist Joe Rao pointed out earlier this week, there is a chance that skywatchers on the Eastern Seaboard could glimpse at least part of the launch after liftoff. You can see his guide here: How to See the SpaceX Launch from the U.S. East Coast.

According to Rao, Saturday's SpaceX launch will travel nearly parallel to the U.S. East Coast as the Falcon 9 rocket makes its way into orbit. So the bright glow from the rocket's nine Merlin first-stage engines could be visible to observers along the coastline, but the degree of visibility depends on location and local weather conditions. 

Where You Should Look

According to Rao, the Falcon 9 rocket's glow could be visible to observers anywhere between a few seconds after liftoff to up to 3 minutes into the flight. Here is Rao's guide of when and where to look based on your observing location in order to see the SpaceX.

  • Southeast U.S. coastline: For locations north of Cape Canaveral, Florida, viewers should initially concentrate on the south-southwest horizon. If you are south of the Cape in Florida, look low toward the north-northeast. If you're west of the cape, look low toward the east-northeast. 
  • Mid-Atlantic region: Look to the south about 3 to 6 minutes after liftoff.
  • Northeast: Keep your eyes aimed low toward the south-southeast about 6 to 8 minutes after launch. 

"Depending upon your distance from the coastline, the SpaceX rocket will be relatively low on the horizon — 5 to 15 degrees. (Your clenched fist held at arm's length covers about 10 degrees of sky.)," Rao wrote in his Monday guide. "If you're positioned near the edge of a viewing circle, the rocket will barely come above the horizon and could be obscured by low clouds or haze."
