Alex,

it isn't man-made.

Jason,

the H value of the object is 27.0 which translates to ~24-m if it has an albedo
of 5%. I chose 60 feet for the conversion because I'm guessing its a little
darker than 5%.

I've input some of the parameters into the Earth Impact Effects Program tool at:

http://www.lpl.arizona.edu/impacteffects/

I did use an iron, but used average parameters, 17km velocity, 45 degree entry,
20 km distance. You can see the results of my inputs here.

I have to head out in a few minutes, but if someone wants to take the time to
input the correct inputs for this object, it'd be interesting to see the results.
