Program: GS-2008A-DD-5

Our team has been conducting a search at high-ecliptic latitudes for highly-inclined Kuiper Belt objects using the Megaprime mosaic on CFHT. In data acquired May 31st 2008 we have discovered an object (with internal designation HL8n1) with an extreme orbital inclination. Tracking observations from the MMT 6.5-m on June 23rd indicate that this object has an orbital inclination of 99 +/- 4 degrees. This orbit, essentially perpendicular to the plane of the Solar System, and retrograde, is unique. This Director's Discretionary request is for urgent observations (1 hour of telescope time) to further constrain the object's orbit and to prevent its loss.
