As part of our multi-observatory , multi-filter campaign , we present r-i color observations of 82 Near-Earth Objects ( NEOs ) obtained with the RATIR instrument on the 1.5 m robotic telescope at the San Pedro Martir ’ s National Observatory in Mexico .
Our project is particularly focused on rapid response observations of small ( \lesssim 850 m ) NEOs .
The rapid response and the use of spectrophotometry allows us to constrain the taxonomic classification of NEOs with high efficiency .
Here we present the methodology of our observations and our result , suggesting that the ratio of C-type to S-type asteroids in a size range of \sim 30-850m is 1.1 , which is in accordance with our previous results .
We also find that 10 \% of all NEOs in our sample are neither C- nor S-type asteroids
