This object posted on the NEOCP moving at 3"/min the longest exposure to get the object image un trailed was only 20 seconds, at magnitud around 19V was quite challenging for my 0.40 m telescope, staking three sets of 20 images each the object was quite obvious with a good signal to noise ratio to perform astrometry. Also the PC's clock was synched with ntp protocol to a time server of the Paris observatory to an accuracy better than .1 sec. This is the first time I contribute confirming a discovery by the F51 Pan-STARRS-1 at Haleakala. Looking at the dispersion of the photometry so far I'd say this may be a fast rotator asteroid, further photometry would be interesting.
The orbit resulting from the observations so far is that of an unusual mars-crossing object with a semi-axis a=2.65, high eccentricity e=0.49 and high inclination i = 25.
