NEA 1998 TU3, 5 Oct 2010

A 5.2km diameter lump of rock, currently situated about 0.193 A.U. from Earth - not considered a potentially hazardous asteroid.

It is well situated for southern observers and is a relatively easy one to image with basic gear - it's bright (mag 12.6, heading to mag 12.4 in mid-month), with slow sky motion allowing longer exposures. That's not to say I've done it particularly well, LOL!

The following composite tracks its motion over 25 minutes - 80 sec exposures were used, piggybacked Canon 400D at 200mm, hand-guided through reticle on unmotorised EQ1 mount.
