Note at time of upload 2015 PU228 is  listed on the "Sentry Risk Table"  and the  "NEODyS CLOMON2 risk page"  as  Torino Scale   1. 

HOWEVER this  is NOT a prediction of an  impact  but rather a statement there is insufficient observational data rule out  an impact on 2081-01-15.40  With additional observations this asteroid  will likely  be re-assignment to Torino Scale   0.

Torino Scale

at the time of upload the chance the asteroid will MISS the Earth is 99.9928%

Confirmation Images of the Near-Earth Object 2015 PK9 on 2015-08-10

The Near-Earth Object  2015 PK9 (Orbit type: Apollo ) was first observed at SONEAR Observatory, Oliveira.(MPC code Y00)  on 2015 08 10.10036. The asteroid has an approximate diameter 49 m - 110 m ( Absolute Magnitude:  H= 23.651). This  asteroid made  a close-approach  to Earth on 2015-08-07 Nominal Distance (AU) : 0.0148213183067307 (5.768 Lunar Distances). The asteroid's  Earth MOID (Minimum Orbit Intersection Distance) is  0.013686 AU (5.326 Lunar Distances). The last published Observations was made at: 2015 08 11.54955. At the time of this 122 observations have been made and the orbit has as uncertainty of  6.
