Here's a couple of stacked images I took of the asteroid. I dailed into T-18 on the itelescope network in Spain and took a series of 60 second exposures of the asteroid. For the first run I did 5 exposures back to back and for the second I did 3 exposures (though for the second one some thin clouds were starting to come in).

The asteroid is a series of dashed lines in each image, each dash is the asteroid moving over the course of one of the exposures that make up the image. It's hauling ass, and if you look closely you can see that the dashes are slightly longer in the second image than the first because it's getting closer to earth with every minute.
