Confirmation Images of the Asteroid 2015 RV1 on 2015-09-05

The Near-Earth Object 2015 RV1 (Orbit type: Amor ) was first observed at ISON-SSO Observatory, Siding Spring. (MPC code Q60) by L. Elenin. using a 0.4-m f/2.4 reflector + CCD. on 2015 09 04.44091. The asteroid has an approximate diameter 270 m to 750 m ( Absolute Magnitude: H= 19.722) The asteroid's Earth MOID (Minimum Orbit Intersection Distance) is 0.360167 AU (140.167 Lunar Distances). The last published Observations was made at: 2015 09 07.9515. At the time of this post 62 observations have been made.

While 2015 RV1 was on the NEO Confirmation Page in an effort to help in the confirmation I was able to obtain 18--- 60 Second Luminance BIN2 Images on itelescope.net's (TEL T27 0.70-m f/6.6 CDK astrograph + CCD) , at Siding Spring Observatory, Coonabarabran, NSW, Australia. (MPC Q62) and did did data reduction on four images.(working around stars)

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%
