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%

Observing Run of 2015 PU228  on 2015-08-24 from Nerpio Spain
 On 2015-08-24 I was able to obtain 17 -- 60 Second Luminance BIN2 Images on itelescope.net's (TEL T7 0.43-m f/6.8 astrograph + CCD)  at AstroCamp Observatory. Nerpio, Spain  (MPC Code  I89)  and created 3 stacks of  5 images
