[2][7] After more observations, astronomers determined that the object would impact Earth on 13 November 2015 at 06:18 UTC (11:48 local time),[9] south of Sri Lanka.

[2][7] Due to its small size, it was expected that most or all of the object would burn up in the atmosphere before impacting, but would be visible as a bright daytime fireball if the sky was not badly overcast.

[18] For observers in Colombo, Sri Lanka, the object started out[clarification needed] 30 degrees above the horizon coming in from slightly south of due west.

Scientists wanted to study WT1190F to better understand the trajectory and atmospheric entry of satellites, debris, and small asteroids from translunar orbit.

[20][8] The International Astronomical Center (IAC) and the United Arab Emirates Space Agency utilized a Gulfstream 450 jet to study the re-entry from above the clouds and haze.

[9][21] The International Astronomical Center (IAC) and the United Arab Emirates Space Agency observed WT1190F as it fell towards the Earth.

The IAC chartered a Gulfstream 450 jet to bring researchers such as Peter Jenniskens to the area of WT1190F's impact, at a high altitude, to view the event over clouds or haze.

[20] The Next TC3 Consortium Asteroid Detection and Early Warning team narrowed the atmospheric entry time to ± 1.3 seconds.
