OPPORTUNITY UPDATE: sols 3166-3173, Dec. 19, 2012-Dec. 26, 2012: Working 
Through The Holidays

Opportunity is on the inboard edge of "Cape York" on the rim of Endeavour Crater, 
positioned at a location called "Copper Cliff."

Over the long holiday period, the rover has been stationary and conducting 
in-situ (contact) science investigations with the robotic arm instruments, 
including the Microscopic Imager (MI) and Alpha Particle X-ray Spectrometer 
(APXS). Assessments of atmospheric opacity and measurements of atmospheric 
argon are also being performed.

As of Sol 3173 (Dec. 19, 2012), the solar array energy production was down to 
485 watt-hours, with an increased atmospheric opacity (Tau) of 1.02 and a solar 
array dust factor of 0.594.

Total odometry is 22.02 miles (35438.37 meters).
