Near Earth Asteroid 2012 LZ1 10:10 UT, 15 June 2012

2012 LZ1 imaged with iTelescope T14 on June 15, 2012 10:10 UT. The image is a stack of 7x120 second exposures, stretched in  FITS Liberator and stacked with  ImageJ. Click to embiggen (it's not as big as my previous image, but worth it)

NEO 2012 LZ1 was imaged here at 10:10 UT, nearly 11 hours after its closest approach of 13-14 lunar-distances (that's the distance between the Earth and the Moon, 0.036 AU) on June 14 23:10 UT. The asteroid is just zipping past the faint globular cluster PAL 11 when this series of images were taken.

I was trying for a longer series of images to make a really cool animation, but the oncoming twilight put paid to that.

Here's my animation.
