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
