Asteroid trackers at the observatory were able to observe the space rock for two days before their views were disrupted by bad weather.
As a result of the mishap, there was some uncertainty about the space rock’s orbit.
NASA has since ruled out any major risk of impact, including on the two dates in 2029 and 2036.
Don Yeomans of NASA’s Near-Earth Object Program Office said: “With the new data provided by the Magdalena Ridge and the Pan-STARRS optical observatories, along with very recent data provided by the Goldstone Solar System Radar, we have effectively ruled out the possibility of an Earth impact by Apophis in 2036.
