NOTE: A digital artifact appeared in three images (1,2,and 3) "near" (436724) 2011 UW158 however it was within 0.3 a pixels of have the SAME Pixel Coordinate (x/y) in ALL three images -- I dither the images so this could ruled out-- it being anything in orbit.

The Asteroid (387733) 2003 GS during the total lunar eclipse of 2014-04-15.


The Asteroid (387733) 2003 GS during the total lunar eclipse of 2014-04-15. The idea was to take advantage of the total lunar eclipse get useful images of a "desirable" NEO. The moon position was within 25 degrees from the imaging target ((387733) 2003 GS).... if this was a "normal" full moon It would have mostly likely been too "close" to get "good" Images.
