Asteroid 2014 JO25 recedes from view (20 April, 2017)

| Asteroid 2014 JO25 ziping along with the scope tracking on the asteroid (the asteroid is the dot near the edge). 20 x 60 second luminance exposures with iTelescope T11 stacked and aligned in ImageJ. Imaging starts at 9:05 UT (3:05 am local time 20th) Click to embiggen. | Animation of the same 20 x 60 frames (click to embiggen for animated asteroidal goodness) |
As Asteroid 2014 JO25 recedes from earth I was able to get some more images and animations. By the time I took the above images with iTelescope T11 in New Mexico, it had moved far enough away that I could track on the asteroid. Still moving at a fair clip and the stars are trailed.

| Asteroid 2014 JO25 zips along receding from Earth with added satellite trails (the asteroid is the dotted line through the centre). 20 x 60 second luminance exposures with iTelescope T14 stacked and aligned in ImageJ. Imaging starts at 3:05 UT (9:05 pm local time 19th) Click to embiggen. | Animation of the same 20 x 60 frames (click to embiggen for animated asteroidal goodness) |
Earlier in the UT day from T14, also New Mexico. Asteroid is moving too fast to track.

| Asteroid 2014 JO25 near galaxy NGC 4710. 7 x 120 second luminance exposures with iTelescope T13 (Siding Spring Observaory) stacked and aligned in ImageJ. Imaging starts at 11:00 UT (9:05 pm local time 20th) Click to embiggen and see more galaxies. | Animation of the same 20 x 60 frames (click to embiggen for animated asteroidal goodness). Cloud comes over in the last frames. |
Finally an image from telescope T13 at Siding Spring Observatory in Australia, choosing to track on the galaxies rather than the asteroid for a prettier composition. Clouds have ruined any chance of me seeing the asteroid with my own instruments.
