Was the right side plume supposed to change partway through the burn like that?

Orbital ATK-Developed Launch Abort Motor Test Qualifies Motor for Flight, Ensures Astronaut Safety
Dulles, Virginia 15 June 2017 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, along with NASA and Lockheed Martin (NYSE: LMT), successfully performed a ground firing test of the abort motor for NASA’s Orion spacecraft Launch Abort System (LAS) at Orbital ATK’s facility in Promontory, Utah. The launch abort motor is a major part of the LAS, which provides a tremendous enhancement in spaceflight safety for astronauts.
The abort motor, which stands over 17 feet tall and spans three feet in diameter, has a manifold with four exhaust nozzles. It was fixed into a vertical test stand with its nozzles pointing skyward. Upon ignition, the abort motor fired for five seconds with the exhaust plume flames reaching up to 100 feet in height. The high-impulse motor was specifically developed so the majority of its propellant would be expended in the first three seconds, burning three times faster than a typical motor of this size and delivering the thrust needed to pull the crew module safely away from its launch vehicle. The motor reached 400,000 pounds of thrust in one eighth of a second, as expected.
Orbital ATK’s next major abort motor milestones include the QM-2 launch abort motor test firing scheduled for late next year in Utah, and the Ascent Abort-2 Flight Test (AA-2) scheduled to take place at Cape Canaveral Air Force Station, Florida, in 2019. Previous large-scale tests of the launch abort motor include a development motor test in 2008 and a test of the complete LAS in 2010.
Orbital ATK is responsible for the launch abort motor through a contract to Lockheed Martin – Orion’s prime contractor. The Orion LAS program is managed out of NASA’s Langley Research Center in Virginia. Orbital ATK produces the abort motor at its Magna, Utah, facility and the attitude control motor at its Elkton, Maryland, facility. The company also manufactures the composite case for the abort motor at its facility in Clearfield, Utah.
