[Update 2: 20200315_133158 UTC: Today's launch was aborted at T:+0:00, due to "Launch abort on engine high power". No word, yet, on when a retry will be attempted.--martyb]
[Update 3: 20200315_195221 UTC: SpaceX tweet: "Standing down today; standard auto-abort triggered due to out of family data during engine power check. Will announce next launch date opportunity once confirmed on the Range". In response to a query "Out of family?", User Viv replied: "Data from sensors & system isn't always the same, but if you plot it on a graph, all nominal data will be one big cluster aka family. If readings from sensors or systems are not within this cluster, they're out of family, eg something might be wrong w sensors or system itself". For those who missed it, here is a brief video that shows a few seconds bracketing the scheduled launch countdown and abort.

Watch Live: SpaceX attempts to launch the same Falcon 9 a fifth time:
In launching its next batch of Starlink satellites-the company's sixth batch of 60 operational spacecraft-SpaceX plans to continue to push the bounds of reuse. With this mission, for the first time, the company plans to fly the same Falcon 9 first stage for the fifth time.
After completing a static fire test of its Falcon 9 rocket's first stage on Friday, the company is now targeting Sunday at 9:22am ET (13:22 UTC) for the mission from Launch Complex 39A at Kennedy Space Center. The weather is expected to be favorable, with only a 10 percent chance of poor conditions due to too many cumulus clouds.
SpaceX also announced on Friday that it will reuse the rocket's payload fairing, which previously flew on a Starlink mission in May 2019. This means that the only part of the Falcon 9 rocket not being recycled is its second stage, which is powered by a single Merlin vacuum engine and pushes the satellites from the edge of space to their deployment into an orbit more than 200km above the ground.
[...] For Sunday's launch attempt, SpaceX will attempt to recover this first stage on a drone ship in the Atlantic Ocean. It will also attempt to retrieve the fairing halves. This will be the sixth launch of the year for SpaceX.
According to SpaceFlighNow's launch schedule:
Launch time: 1322 GMT (9:22 a.m. EDT)
Launch site: LC-39A, Kennedy Space Center, FloridaA SpaceX Falcon 9 rocket is expected to launch the sixth batch of approximately 60 satellites for SpaceX's Starlink broadband network, a mission designated Starlink 5.
The launch will be live-streamed on YouTube; the feed usually starts about 20 minutes before launch time.
