On the minorplanetcenter.net web site, you can search for asteroids, and it will produce a list of observations, including when and where. One place in particular, the Zwicky Transient Facility on Mount Palomar, keeps all of its images on-line, and it will let you download them.
So, I found a couple of images from this past May. The problem is that the images are very large, and the stars are incredibly tiny. I also found some software that will align a pair of images and then rapidly (3 times a second) alternate between two. Anything that has moved with then show up on one image in one position and not in the other. This “blinking” procedure is fairly effective, and is a technique used by astronomers for over a century.
But I still couldn’t find it. So, I used Stellarium, a computer based planetarium program and found its position at the time of the exposures (they’re taken 90 seconds apart). Then I had to match up a rotated, and mirror-imaged, picture until I could get the approximate position.
Once I’d found it (which I had to do several times because I kept losing it), I was able to crop the two images from the ZTF ‘scope and create an animated GIF, which I then pushed through some other software to annotate it, resulting in the image here.
The image is a portion of the sky 6.76 x 8.72 arc minutes in size.
