I would like to image this thing. Any idea what constellation it will be in the night of the 27th? -David On 6/24/2011 9:13 AM, Barrett wrote:

Bend it Like Beckham! Small Asteroid to Whip Past Earth on June 27, 2011 Don Yeomans& Paul Chodas NASA/JPL Near-Earth Object Program Office June 23, 2011
Trajectory of 2011 MD projected onto the Earth's orbital plane. Note from this viewing angle, the asteroid passes underneath the Earth.
Trajectory of 2011 MD from the general direction of the Sun.
Near-Earth asteroid 2011 MD will pass only 12,000 kilometers (7,500 miles) above the Earth's surface on Monday June 27 at about 9:30 EDT. The asteroid was discovered by the LINEAR near-Earth object discovery team observing from Socorro, New Mexico. The diagram on the left shows the trajectory of 2011 MD projected onto the Earth's orbital plane over a four-day interval. The diagram on the left gives another view from the general direction of the Sun that indicates that 2011 MD will reach its closest Earth approach point in extreme southern latitudes (in fact over the southern Atlantic Ocean). This small asteroid, only 5-20 meters in diameter, is in a very Earth-like orbit about the Sun, but an orbital analysis indicates there is no chance it will actually strike Earth on Monday. The incoming trajectory leg passes several thousand kilometers outside the geosynchronous ring of satellites and the outgoing leg passes well inside the ring. One would expect an object of this size to come this close to Earth about every 6 years on average. For a brief time, it will be bright enough to be seen even with a modest-sized telescope.

24 June 2011Breaking News Alert! O! NEOs to Rock, Rattle, and Roll 2011MD VERY Close Approach 27JUN2011 Alert! NEOs Rock, Rattle, and Roll! Green Meteor Fireballs and Maybe a Bolide or more! (Issued 24JUN2011 1:30 am Tokyo by LunarMeteorite*Hunter) This is an alert; we will have a very close visitor, (2011 MD) 2011-Jun-27 0.0001 0.05LD 8.0 m - 18 m 27.6 6.77 within ~19,200km or 12,000 miles (about the distance from New Zealand to Great Britian - NOT far by space standards) on 27JUN2011! I expect we will see many large fireball events just prior to from today until July 5! Have your pointed and ready to capture and IF you have time get outside and observe and you might get lucky!
