NEO 2010 NR1
Published - http://www.minorplanetcenter.org/mpec/K10/K10N46.html
This NEO appeared on the NEO Confirmation Page around July 9, 2010 and I collected the brief information below with a TOA-150 (6" refractor) and a STL-6306 CCD Imager - through the Tzec Maun Foundation.
Confirmation images and observations of this object were obtained on July 10, 2010. They are found below.

The image above is a single three-minute exposure.
A second set of images were acquired of this object and later submitted to the Minor Planet Center for further confirmation images.

Also in the field, were two other measurable asteroids - and they too were measured and observations were submitted to the Minor Planet Center. Observations can be found below. As with all of my images, I measure ALL objects in the fields to further utilize the images and attempt to gather photometry for newly discovered NEO's since it is sometimes years before they are seen again. With newly discovered Near Earth Objects, I try to make attempts to "at least" obtain a rough estimate of their rotational periods.

Rough Photometry of 2010NR1
Since I only had 14 images of 2010NR1 to work with, I was able to obtain a short photometrical calculation of 2010NR1. If more images are collected it will improve the lightcurve of this object. Below is what I calculated from the 14 images over a period of around one hour.
Raw Plot of 2010NR1
Phased Plot of 2010NR1
According to the plot from only 14 observations of 2010NR1, this object has a rotational period of 0.89 ± 0.04 hours. This object also has a H Value (absolute magnitude) of 21.9 which puts it in the range of 110 to 240 meters. With a rotational period of 0.89 hours, this object is likely that of a monolithic minor planet rather than that of a rubble pile. If it were a rubble pile asteroid (RPA) it would probably not be able to hold itself together at this rotational speed.
The images used were composed of three minute exposures.
